Fix aarch64 handling of error code.
In the is_signal_frame call, there is an error return path that can
return a non-zero value. Unfortunately, only zero is considered an
error, so this causes the frame to be handled incorrectly.
Once this was fixed, I also modified the code so that if the treating
the unwind as in a signal frame fails, we can fall back and try a couple
of different paths.
It turns out this is_signal_frame check was broken on arm too.

Add basic support for the QNX operating system
This change adds some special cases to allow libunwind to compile
for QNX.
* QNX's copy of <elf.h> and <link.h> reside in sys/ instead. To deal
with this, an AC_CHECK_HEADERS() was added to check for the files
in both locations.
* Similarly, QNX does not have <endian.h>. In cases where the file is
not found, logic was added to refer to QNX-specific macros to determine
endianness.
* The QCC compiler, which is a wrapper around GCC, cannot handle some
standard GCC options. Therefore, logic was added to check for QCC,
and when it is found, to suppress the use of -lgcc, and to express the
option -nostartfiles as -Wc,-nostartfiles instead, which is correctly
passed on to the underlying GCC.
* Finally, the support file os-qnx.c was added, patterned after the existing
os-*.c files. Only local image lookup is currently supported (see the
comments for more information), but this is sufficient for QNX, since
ptrace is not supported there anyway, and that is the only case where the
function is required to do remote image lookup.

Add support for RT signal frame detection on ARM.
This patch adds a few more patterns to the check that detects if the IP
points to a sigreturn sequence.

Implements a check for call to sigreturn that the kernel will have
setup before jumping to the signal handler.

Add initial ARM and MIPS support. To support this, also enable the
reading of .debug_frame sections (used in lieu of .eh_frame sections
when they're not available).
