This is a backport of commit revision 151568 from trunk into 4.4
the changes for config/t-slibgcc-elf-ver are already available in 4.4
and t-slibgcc-libgcc is available in 4.4.4
so they dont reflect in the patch as they are mentioned in the changelog
message. 

This patch converts the libgcc_s.so to a linker script stub which should
let static libgcc link in on affected architectures they should include
t-slibgcc-libgcc in there tmake_file variable. For OE its ppc for now
which has this problem when using libtool and -Os flag.
