Prefer MACHNE_CPUARCH to MACHINE_ARCH in most contexts where you want
to test of all the CPUs of a given family conform.

ea246b6369 On shared object unload, in __cxa_finalize, call and clear all installed
atexit and __cxa_atexit handlers that are either installed by unloaded
dso, or points to the functions provided by the dso.

Use _rtld_addr_phdr to locate segment information from the address of
private variable belonging to the dso, supplied by crtstuff.c. Provide
utility function __elf_phdr_match_addr to do the match of address against
dso executable segment.

Call back into libthr from __cxa_finalize using weak
__pthread_cxa_finalize symbol to remove any atfork handler which
function points into unloaded object.

The rtld needs private __pthread_cxa_finalize symbol to not require
resolution of the weak undefined symbol at initialization time. This
cannot work, since rtld is relocated before sym_zero is set up.

271e7c594b Disable all warnings when building gdtoa. This allows building libc with
clang.
The general idea is that the vendor will not accept our compilation
patches and so disabling the warnings is the best way to go as it makes
future imports bearable.

8869de5e55 The 64-bit PowerPC ABI implemented in binutils 2.15 requires some special
quirks for weak-symbol handling. Text symbols require also marking weak
the special dot-symbol associated with the function, and data symbols
require that you not do that. To fix this, provide a hacked
__weak_reference for powerpc64, and define a new __weak_reference_data
for the single weak data symbol in base.

af448c52e4 Simplify the calculation of s_scale by rewriting the FP expression to

c5e0ba5fe4 On powerpc, calculate s_scale using the non-FP version previously
specific to hp300. Since FreeBSD does not support hp300, hp300 has
been removed from the condition altogether.

The FP version broke profiling on powerpc due to invalid results.
Casting to double instead of float resolved the issue, but with
Book-E not having a FP unit, the non-FP version looked preferrable.
Note that even on AIM hardware the FP version yielded an invalid
value for s_scale, so the problem is most likely with the compiler
or with the expression itself.

ff847ecb82 In threaded processes, destroy the mutex atexit_mutex when we've
finished using it.  This allows the mutex's allocated memory to be
freed.

This is one sense a rather silly change, since at this point we're
less than a microsecond away from calling _exit; but fixing this
memory leak is likely to make life easier for anyone trying to
track down other memory leaks.
