util/crossgcc: Add bootstrap-only mode

buildgcc -B (--bootstrap-only) builds only a bootstrap compiler. That
useful if you want to package the cross compilers: first build the
bootstrap compiler, then all required cross compilers in a separate
directory (using the bootstrap compiler through an adjusted PATH).
