microblaze: extable: sort the exception table at build time
Sort the exception table at build-time rather than during boot.
Microblaze is the same case as AARCH64 that's why EM_MICROBLAZE
conditional check was added to allow cross-compilation on machines which
are not running the latest libc-dev.
Inspired by AARCH64 commit adace89562c7 ("arm64: extable: sort the
exception table at build time").

scripts/sortextable: support objects with more than 64K sections.
Building with a large config and -ffunction-sections results in a large
number of sections and sortextable needs to be able to handle that.
Implement support for > 64K sections as modpost does.

arm64: extable: sort the exception table at build time
As is done for other architectures, sort the exception table at
build-time rather than during boot.
Since sortextable appears to be a standalone C program relying on the
host elf.h to provide EM_AARCH64, I've had to add a conditional check in
order to allow cross-compilation on machines that aren't running a
bleeding-edge libc-dev.

ARM: 7568/1: Sort exception table at compile time
Add the ARM machine identifier to sortextable and select the
config option so that we can sort the exception table at compile
time. sortextable relies on a section named __ex_table existing
in the vmlinux, but ARM's linker script places the exception
table in the data section. Give the exception table its own
section so that sortextable can find it.
This allows us to skip the sorting step during boot.

scripts/sortextable: Handle relative entries, and other cleanups
x86 is now using relative rather than absolute addresses in its
exception table, so we add a sorter for these. If there are
relocations on the __ex_table section, they are redundant and probably
incorrect after the sort, so they are zeroed out leaving them valid
and consistent.
Also use the unaligned safe accessors from tools/{be,le}_byteshift.h
