Need to use some library path before /usr/lib

That looks quite nice, and I was going to use that, alas I cannot
seem to make it work.  Is it possible that libmap.conf does not work
when the name on the left-hand side is the same as on the right-hand
side?

It wouldn't really help since the resulting binaries need the very same 
workaround.

That might work, though it looks like a lot of work.  It occurs to me
we really need to set this globally.  That is one of the implications
those that always pushed for having ports use a distinct compiler may
have missed.  That, or using -rpath.

Loren, how would we best have GCC automatically add 
  -rpath=/usr/local/lib/gcc44
to every invocation?  Presumably spec magic?
