Fix uses of -fPIC and -fPIE.
We've been using -fPIC and -fPIE together in the global cflags all this
time. These options are incompatible. The only reason we haven't been
hit by this before is because of the forced -Bsymbolic in GCC. To fix
this, pass -fpic when compiling objects for shared libraries and -fpie
when compiling objects for executables. For static libraries, also use
-fpic. We have to do this because static libraries might be included in
either a shared library or an executable. Code compiled with -fpie
cannot be included in a shared library, but code compiled with -fpic
may be included in an executable.
We've also been using -fpic and -fPIC together. These are different
options, and only the latter will take effect.
http://stackoverflow.com/a/967010
The final thing this fixes is that we had -f(PIC|PIE) flags being passed
to link commands. These are compile time flags, and don't do anything at
link time.

Add -latomic to all target builds
Projects using stdatomic.h needs libatomic.a in case compiler can't
expand all __atomic* intrinsics. eg, __atomic_is_lock_free in
armeabi/mips.
Adding libatomic.a globally makes more sense than adding
"LOCAL_LDLIB += -latomic " in each project including <stdatomic.h>.
Projects don't need atomic operations won't get redundant DT_NEEDED

Disable canonical prefixes of system headers
GCC know a few pre-defined paths (relative to its location) to
search for headers, libraries, program, etc. By default GCC prefixes
its own path(argv[0]) and calls realpath() which result in absolute
path with all symlink, . and .. removed.
It's usually good to have canonicalised paths, but absolute paths
in *.d file can cause unnecessary relinking when stale entries
in ccache cache hit
Add -no-canonical-prefixes (gcc>=4.6) and
-fno-canonical-system-headers (gcc>4.6) to disable realpath() on
prefixed paths

Load compiler environment for a second arch.
This is the first step to build 32-bit libraries in a 64-bit product.
It will work like this:
1) In the product's BoardConfig.mk, define:
TARGET_2ND_ARCH, TARGET_2ND_ARCH_VARIANT, TARGET_2ND_CPU_VARIANT.
The build system uses those variables to set up an additional compiler
environment for the second arch.
2) When parsing Android.mks, the build system sets up rules to build a
module for both the 1st arch and the 2nd arch, unless it's explicitly
asked to skip so.
Android.mk will be adapted if there is additional rule of generating
source files.
The build system will accept arch-specific LOCAL_ variables, such as
LOCAL_CFLAGS_arm, LOCAL_CFLAGS_armv7-a-neon, LOCAL_CFLAGS_cortex-a15,
LOCAL_CFLAGS_aarch64 etc. Modules use such variables to set up build for
various archs at the same time.
3) Install binary of the 2nd arch by adding "<module_name>:32" to
PRODUCT_PACKAGES. All 2nd-arch libraries linked in by "<module_name>:32"
will be installed automatically.

Add a "reverse AUX hack" for ARM.
MIPS and x86 are almost completely switched over to uapi-only. ARM is still
currently old-only. A cleanup of the uapi headers over the weekend means
that the uapi-only <linux/kexec.h> is now in the right place, which will break
the ARM build unless the ARM build also looks in the uapi headers if it can't
find an old header.

arm: turn on -Wl,--fatal-warnings
Third time's the charm. :-)
In b238210c0172e771b1302364273016ad1fabafb8, we added
-Wl,--warn-shared-textrel to TARGET_GLOBAL_LDFLAGS. This generated
a warning whenever we created a shared library with a text
relocation. At the time, we wrote:
=====
Emit a warning when the static linker detects a shared library
has text relocations. Text relocations make it harder to
share pages across processes, and make it harder to use
certain memory protection features in, for example, SELinux.
This warning will turn into an error in a future change
(via --fatal-warnings)
=====
All code which uses text relocations has either been fixed, or
we've temporarily worked around the issue so the code can still
compile.
Enable --fatal-warnings.
This reverts commit 942167dab8345c420b205ce9b9b6b4fc779a7583.

enable PIE for dynamically linked executables
Compile all programs on Android with -fPIE and -pie. This enables
PIE (Position Independent Executables), which helps protect Android
applications from exploitation due to memory management bugs.
Stop using the armelf.x linker script. This script hard codes the
load address of the executable, defeating the position independence
PIE requires.
Note: PIE *static* executables are not supported at this time and
require additional linker changes.

Add .gnu_debuglink when stripping DSOs.
This is used by debug tools to find symbols for the stripped binary.
Adds ~70 bytes to each DSO, ~25000 bytes total, which is about 0.01% of the
system image.
This change only affects -eng and -userdebug builds, and does not affect -user.

Lunch: don't use a toolchain that doesn't exist.
"lunch sdk-eng" on cygwin tries to use a gcc.exe from the
prebuild arm toolchain, but it doesn't exist. This prevents
from setting variables to point on a gcc toolchain if there
is none for the given arch.

build: remove prelinker build build system
This patch removes support for prelinking from the build system. By now, the
prelinker has outlived its usefulness for several reasons. Firstly, the
speedup that it afforded in the early days of Android is now nullified by the
speed of hardware, as well as by the presence of Zygote. Secondly, the space
savings that come with prelinking (measued at 17MB on a recent honeycomb
stingray build) are no longer important either. Thirdly, prelinking reduces
the effectiveness of Address-Space-Layout Randomization. Finally, since it is
not part of the gcc suite, the prelinker needs to be maintained separately.
The patch deletes apriori, soslim, lsd, isprelinked, and iself from the source
tree. It also removes the prelink map.
LOCAL_PRELINK_MODULE becomes a no-op. Individual Android.mk will get cleaned
separately. Support for prelinking will have to be removed from the recovery
code and from the dynamic loader as well.

Remove global inline options.
The purpose of removing global inline options is to give
compiler the opportunity to do inline optimizations and inline
tunings for Android native codes.
By removing these global inline options now, the size of
almost all native libraries are reduced. And there is no
noticable performance degradation on webkit, gcstone and
skia benchmarks.

Make arm-linux-androideabi toolchain the default for Android build.
androideabi target is already in upstream GCC. The arm-linux-
androideabi toolchain can be built directly from upstream GCC.
Switching from old special tailored arm-eabi toolchain to the new
arm-linux-androideabi toolchain make us closer to the opensource
community and friendly to all toolchain developers.
kernel still uses arm-eabi toolchain. So we add arm-eabi toolchain
path to PATH.
The arm-linux-androideabi-4.4.x toolchain is built with the same
source as the latest arm-eabi-4.4.3 toolchain except for the
target change patches.

Group needed libraries together to solve the cyclic dependence
between libc, libc_nomalloc and libgcc. When building with upcoming
arm-linux-androideabi toolchain, Symbol raise is needed by libgcc.a
and defined by libc.a or libc_nomalloc.a.which.
This patch groups libgc.a, libc_nomalloc.a and libgcc.a together, which is
a minimal group to solve this problem.

Switch toolchain from gcc-4.4.0 to gcc-4.4.3
gcc-4.4.3 toolchain is based on fsf GCC-4.4.3 with numerous patches.
It reduces 3.65% code size than the prebuilt gcc-4.4.0 toolchain,
and improves 3.4% performance on Android benchmarks.
The toolchain uses gold as default linker. With gold, the toolchain
further reduces 1MB system image.

Get rid of $(combo_target)
The only OS-ARCH combo that would have benefited from it
is linux-x86, but it explicitly used separate configurations
for the HOST_ and TARGET_ side of things.
This makes is clear which files are related to the HOST_
configuration and which ones are related to the TARGET_
configuration, and expands $(combo_target) to the only
possible/reasonable value that it could have had in every
file.
This also cleans up the simulator, by moving it in a single
place in TARGET_linux_x86 (since the only part that's special
is to use HOST_ settings even when building TARGET_ modules).
