The compiler.h header defines two macros INCBIN and
INCFILE that can be used to include binary files
into C sources. This patch fixes a few issues with them:
* The .align directive is equivalent to .p2align
on some architectures (ARM/AArch64) and to .balign
on others (x86). INCBIN previously used .align and
now uses .balign for correct alignment.
* .align 1 enforces a 2-byte alignment on ARM/AArch64,
which caused the _end symbol for the binary to be off
by 1 byte in some cases, which the macro previously
accounted for (incorrectly). With the correct .balign
directive the extra byte is never added, so the size
is now correctly computed without the -1 addend.
* INCBIN should end in a .previous directive
to restore the previous section, since the macro
starts with .section.
