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.
