sometimes rebuilding gcc can be a bit tricky and I think thats what
might have happened in your case. So please rebuild the toolchain

bitbake -c clean eglibc eglibc-initial gcc-cross-initial
gcc-cross-intermediate gcc-cross gcc
bitbake <your image>

that should help if the cross compiler was broken by  unstaging.
