I never tried it for native configurations, so I don't know for sure
that there is a problem.  But I was worried if we didn't have this
restriction, people would expect passing --sysroot=/foo to a non-
sysrooted toolchain to have exactly the same meaning as configuring
with --with-sysroot=/foo.  That isn't going to be true without further
surgery because --with-sysroot affects the default search path.  (see
ld/genscripts.sh, for example.)

But to be honest, the main blocker for me is that I don't really know
what --sysroot is supposed to do on a non-sysrooted toolchain.  If this
patch does what's required, then great.  I've no objection to removing
the error.
