[Buildroot] [PATCH] fix gcc install problem on powerpc+soft-float+install_libgcc_s

[angus salkeld]

Hi

I am building with:
gcc-4.3.3
powerpc-8540
soft-float
install libgcc_s
install libstd++

I get the following error:

# These are in /lib, so...
rm -rf /home/anguss/imports/buildroot/project_build_powerpc/r1/root/usr/lib/libgcc_s*.so*
cp -dpf

So here is a patch that fixes it for me.

Note:

1) I only include this for powerpc (maybe it should only check for soft float)?
2) I have removed the ignore "-" from the copy, as it think that it is
   a problem if you want a library installed but it fails to install.
