This patch moves the powerpc-nofpu port and 4xx string functions from
ports to libc.  Together with the diff below for the README update and
one case where file contents need merging into an existing file, the
following git commands do the directory moves (and removal of the file
from which contents were merged):

git mv ports/sysdeps/powerpc/nofpu sysdeps/powerpc/nofpu
git mv ports/sysdeps/powerpc/soft-fp sysdeps/powerpc/soft-fp
git mv ports/sysdeps/powerpc/powerpc32/405 sysdeps/powerpc/powerpc32/405
git mv ports/sysdeps/powerpc/powerpc32/440 sysdeps/powerpc/powerpc32/440
git mv ports/sysdeps/powerpc/powerpc32/464 sysdeps/powerpc/powerpc32/464
git mv ports/sysdeps/powerpc/powerpc32/476 sysdeps/powerpc/powerpc32/476
git rm ports/sysdeps/powerpc/powerpc32/Makefile
git mv ports/sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu
git mv ports/sysdeps/unix/sysv/linux/powerpc/powerpc32/405 sysdeps/unix/sysv/linux/powerpc/powerpc32/405
git mv ports/sysdeps/unix/sysv/linux/powerpc/powerpc32/440 sysdeps/unix/sysv/linux/powerpc/powerpc32/440
git mv ports/sysdeps/unix/sysv/linux/powerpc/powerpc32/464 sysdeps/unix/sysv/linux/powerpc/powerpc32/464
git mv ports/sysdeps/unix/sysv/linux/powerpc/powerpc32/476 sysdeps/unix/sysv/linux/powerpc/powerpc32/476

Tested that for both hard-float and soft-float powerpc32 builds, the
disassembly of installed binaries is the same before and after the
change (paths in debug info are of course different).
