And to amend the above - config.gcc should end with gas/gnu_ld that we assume unless overridden by flags provided to configure. For the solaris case that might mean they are empty, aka unknown, or we still assume they are used and fixup during configure. And we should document the assumption in install.texi (we largely do implicitly by requiring GNU binutils).
