But that's a bug in GCC.  GNU tools are supposed to handle both
forms.

Also, I'd value command-line handling consistency of a tool in itself
over consistency with other tools.  I.e., if GNU ld handles both
forms in general, let's make it handle both in this particular case,
even if GCC doesn't handle them both.

A counter-argument would get me to bring up the fact that GCC handles
-fwhatever as equivalent to --whatever, so how come the
counter-argument doesn't push for -fsysroot= as well? :-)
