Update libstdc++ configuration.

Its been quite a while since the last time we updated this and since then
we have grown iconv and a bunch of complex math functions.

This only applies to the platforms which still use GCC 4.2.1 in the
toolchain.

Teach libstdc++ about logl(3).

The logl(3) family of functions were implemented in r251292.
Define them in libstdc++'s configuration so they can be used.

Regenerate libstdc++'s config.h, synchronizing it with our current

Turn on TLS support for arm on here as it is supported since r231618/
r231619 and working since r233106.

When one attempts to compile the tree with -march=i386, which also used
to be gcc's default before r198344, calls to atomic builtins will not be
expanded inline. Instead, they will be generated as calls to external
functions (e.g. __sync_fetch_and_add_N), leading to linking errors later
on.

Put in a seatbelt that disables use of atomic builtins in libstdc++ and
llvm, when tuning specifically for the real i386 CPU. This does not
protect against all possible issues, but it is better than nothing.

Now that TLS is supported for sparc64 by both binutils 2.17.50 committed
in r218822 and rtld(1) committed in r219533 turn on TLS support in GCC.

GCC defines built-ins for atomic instructions found on i486 and higher.
Because FreeBSD no longer supports the 80386 cpu all code targeting
FreeBSD/i386 necessarily runs on i486 or higher so the compiler
built-ins can be used by default inside libstdc++ and in C++ headers.
This allows newly compiled C++ code to inline some atomic operations.
Old binaries continue to use libstdc++ functions.

Update bmake glue to build GCC 4.2.

Also:
Switch FreeBSD to use libgcc_s.so.1.

Use dl_iterate_phdr to locate shared objects' exception frame
info instead of depending on older register_frame_info machinery.
This allows us to avoid depending on libgcc_s.so.1 in binaries
that do not use exception handling directly. As an additional
benefit it breaks circular libc <=> libgcc_s.so.1 dependency too.

Build newly added libgomp.so.1 library, the runtime support
bits for OpenMP.

Build LGPLed libssp library. Our libc provides our own
BSD-licensed SSP callbacks implementation, so this library
is only built to benefit applications that have hadcoded
knowledge of libssp.so and libssp_nonshared.a. When linked
in from command line, these libraries override libc
implementation.

This commit was manufactured by cvs2svn to create branch 'WIP_GCC31'.
