Remove a lot of unused 64 Bit header stuff.

Follow GNU C Library from c579f48edba88380635ab98cb612030e3ed8691e
and remove the PID caching. These simplifies the architecture specific
assembly code.
The run of the test suite found no regressions, it even solves
some of the test failures for x86/x86_64/sparc.

Ported over from glibc mostly without changes.
Lightly tested with mongrel2 in qemu-system-sparc.

sparc target has assembly implementations of clone.S that doesn't
get used, and thus the build breaks. Also, sparc is missing a header file in
pthreads.old that exists in pthreads.new.

To compile the quad float emulation library gcc needs
__LONG_DOUBLE_128__ macro defined. Check first, if not
supported then revert to the qp_ops.c stubs

Sparc-Gcc generates q_xxx intrinsic calls for quad float ("long double")
code. The routines from glibc's glibc-2.9/sysdeps/sparc/sparc32/soft-fp/*
where taken and ported to uclibc.

* a tweaked clone.S with RESET_PID support
* atomic.h with cmpxchg that works for v8 and beyond

Avoid including akefile.commonarch in each Makefile.arch.
Include it instead from Makefile.in just after the arch specific
Makefile.arch

I got the library to compile with the attached patches, though dynamic
loader crashes early.
In buildroot I changed the architecture name by hand from sparc to
sparc64, otherwise the compiler produced 32-bit files with V9 (64-bit)
instructions. This configuration is not supported by QEMU, so I aimed
for pure 64-bit. I think Sparc64 option needs to be added to
buildroot.
The _Qp_ ops seem to be required by the ABI. This and setjmp patches
are just hacks to get the compilation further. The _Qp_ ops can be
found in glibc, would it be OK to use those?
V9 assembler requires declarations for global register use.
The mem* functions in sparc32 directory did not work. They are
actually used only by the hybrid 32-bit + V9 CPU configuration.

with my config (no locale, the rest enabled). Not tested if libc is complete and usable. All the files listed in *_NO_MULTI need love, best would be to replace all multisources w/ single sources.
