MFC note:
r276646 ("do not erronously export 'openat' symbol from rtld") is not
applicable to stable/10 yet, since PATHFDS support was not merged.
Since the merge of file 5.21 in r276415 and r276416, stable/9 and
stable/10 cannot be built from FreeBSD 8.x. This is because the
build-tools stage requires libmagic, but lib/libmagic/config.h was
generated on head, and it now enables using the xlocale.h APIs, which
are not supported on 8.x (and on 9.x before __FreeBSD_version 900506).
See also the start of this thread on -stable:
https://lists.freebsd.org/pipermail/freebsd-stable/2015-January/081521.html
To fix this, conditionalize the use of xlocale.h APIs to make
bootstrapping from older FreeBSD versions work correctly.

Stop using __FreeBSD_ARCH_armv6__ and switch to __ARM_ARCH >= 6 in the
couple of places in tree. clang already implements ACLE. Add a define
that says we implement version 1.1, even though the implementation
isn't quite complete.
Add support for the __aeabi_c*cmp* functions. These are similar to the
existing functions with the exception they use the condition flags to
store the result.
1) Fix the case we have less arguments for format string than we expected.
2) Return error on unsupported format specs.
(both according to POSIX)
3) For %Z format, understand "UTC" name too.

In ARM asm code, ensure that every ENTRY(foo) has a matching END(foo).
The EABI unwind info requires a .fnend for every .fnstart, and newer
binutils will complain about seeing two .fnstart in a row. This change
allows newer tools to compile our code.
Do not generate unwind info in asm functions if _STANDALONE is defined.
The .fnend op causes the assembler to emit RELOC references to unwind
support functions that don't exist in libstand.
