bootstrap-prefix.sh: disable stage3 gcc bootstrap for RAP stage2 glibc is incompatible with that of stage3. gcc bootstrap does not handle this situation correctly. During bootstrap src_compile(), it passes libstdc++ of new glibc by LD_LIBRARY_PATH to work with g++ of stage2, resulting in symbol conflicts at lease on CentOS 7. The call of `emerge -e @system` will finally build a gcc in bootstrap mode.
