Several versions of gcc have an issue in libstdc++v3 where the build may
clobber stamp-bits with a link to itself. This doesn't manifest itself
on all systems. On several Ubuntu systems, this doesn't appear to be a
problem, but it is an issue on Fedora 16 systems.
To fix the issue, we'll simply filter out stamp-bits from the symlinks
to be generated.
Note: gcc 4.4.7 is unaffected by this issue, so no fix is necessary
there.

This patch ensures that libgcc_s.so properly honours the NOEXECSTACK flag
for MIPS builds, when gcc-linaro-4.8 or 4.9 is the chosen C compiler.

These instructions are for 64-bit load/store. On ARMv5TE, the CPU
requires addresses to be aligned to 64-bit. When misaligned, behavior is
undefined (effectively either loads the same word twice on LDRD, or
corrupts surrounding memory on STRD).
On ARMv6 and newer, unaligned access is safe.
Removing these instructions for ARMv5TE is necessary, because GCC
ignores alignment information in pointers and does unsafe optimizations
that have shown up as bugs in various places.

SPARC builds are currently broken because we do not define the MUSL
dynamic linker name, fix that.
