Remove sysdeps/powerpc/soft-fp

- Subject: Remove sysdeps/powerpc/soft-fp
As discussed in the thread starting at
<http://sourceware.org/ml/libc-ports/2012-05/msg00099.html>,
powerpc-nofpu glibc had some _q_* symbols accidentally added to
version GLIBC_2.2 in glibc 2.4, but they have never been usefully
usable at all and are intended for an ABI incompatible with that
actually used. I propose this patch to remove all these functions as
discussed in that thread. (Despite only being used for a ports
configuration, not for powerpc-fpu, this code is in libc. ports has
its own sysdeps/powerpc/soft-fp directory, containing sfp-machine.h
which is all that's actually needed from such a directory for a
powerpc-nofpu build.)
Tested with a powerpc-nofpu build. With this change, the only
remaining check-abi issues are those I listed for _mcount (a clear
bug) and __fe_nomask_env (where I'd welcome further comment in that
libc-ports thread - note that I don't see why __fe_mask_env or
__fe_nomask_env are declared at all in the public
sysdeps/powerpc/bits/fenv.h header, whatever we do about past ABI
mistakes; the public interface is FE_MASK_ENV and FE_NOMASK_ENV and
fesetenv, and the fpu version of fesetenv calls __fe_nomask_env and
__fe_mask_env internally).
