The .note.android.ident section is only used by GDB, which doesn't
care what section type the section is, but it would be convenient
for readelf -n to be able to find the section too.
The old way of getting the .note.android.ident section to be of type
SH_NOTE involved compiling from .c to .s using gcc, running sed to
change progbits to note, and then compiling from .s to .o using gcc.
Since crtbrand.c only contains a section containing data, a
crtbrand.S can be checked in that will compile on all platforms,
avoiding the need for sed.
Also add crtbrand.o to crtbegin_so.o so that libraries also get
the note, and to the crt workaround in arm libc.so.

crtbrand.c was compiled to a .s file, run through a sed script
to translate a %progbits to %note, and the compiled to .o.
However, when the sed command was copied from the original source
it was not updated to use the new name of the section (.note.ABI-tag
to .note.android.ident), so it didn't modify the file. Since the
section has been generated with type %progbits instead of %note for
two years, just delete the whole sed step.

Include full 16-byte Mips sigset_t signal mask within jump buffer.
Call sigprocmask instead of sigblockmask/sigsetmask to get/set full signal mask.
Include sigsetjmp's savesigs arg inside jmp_buf, instead of following it.
Reserve room for future extensions.
Preserve historically-large mips32 _JBLEN size.
Eliminate redundancy: code setjmp and _setjmp as tail calls into sigsetjmp,
and make longjmp and _longjmp aliases of siglongjmp.

Fix typo in cpu variant makefile depenendency for arm64
Remove libc_static_common_src_files
Share LP32 makefile settings between arches
* changes:

Add <var>_32 to patch-up-arch-specific-flags, and move the LP32
cruft varaibles from the 32-bit arch specific makefiles into the
top level Android.mk.

This is now necessary to build .dat files that are useable for ICU4J as
well, and will need to be used for any future updates of the .dat file:

for LP64 these will be hidden. for LP32 we were cowards and left
them all public for compatibility (though i don't think we ever
dremeled to see whether it was needed). we don't have an easy
way to recognize additions, though, so we can't prevent adding
new turds.
Add a mechanism to prevent the adding of new turds, and use that
mechanism on the fchmod/fchmodat system calls.
