Oh yuck. That means that users cannot install one version of GCC on top of
an older version without knowing precisely which files to delete beforehand
(since we can't do an uninstall). You and I know to always use a different
--prefix for each build, but when everybody else defaults to /usr/local
this won't work.
I still don't understand why we pass -B$prefix/lib to the compiler during
the build, /before/ we install anything in $prefix. I've been told that
this is the Right Thing To Do, but I remain skeptical. :-(
