kexec/powerpc fix optimization for size (gcc -Os) build

crt.S patch had fixes for gcc -Os (optimaze for size), same as
kernel has. Without this fixes powerpc gcc 4.4 generates forever
loop functions for kexec.

This happends because crtsavres code was spit up to individual files
(http://gcc.gnu.org/ml/gcc-patches/2008-03/msg01294.html) and
kexec purgatory code has following options:
--no-undefined -nostartfiles -nostdlib -nodefaultlibs
So in that case crtasaveregs function are not defined and final object
file has been linked without them.  This does not happen with applications
built without -nostdlib, because gcc will add it's standard functions.
