Hmm. I don't think we'll ever have a $PATH containing a path like
c:/..., but there could certainly be paths containing spaces.

This feels rather unpleasant to me. Is it likely that someone will have
programs called llc-3.0 etc, but no llc? If not, I'd suggest that we
just detect llc and they can override which llc gets used with a
--with-llc flag if they want to.
In fact, i think we should do that regardless. After all, we don't try
searching for gcc-4.6 etc either.
Thanks
Ian
