Another possibility might be for us to just add a ./overrides/gcc and
then in our Makefiles export PATH=`pwd`/overrides:${PATH}.  Inside
this gcc override script, we could strip out any offending
-L\s*/usr/lib(/)? and -I\s*/usr/include(/)? occurrences before
calling.

  export PATH=`filter-out-parent-dir ${PATH}`
  exec "$@"

Ugly, but if -L /usr/lib and -I /usr/include are the problem, this
should fix it.  Of course we'd have to symlink to cc, etc. as well for
non-gcc platforms, and this won't help if they don't all use -L and
-I :/

Ahh, that makes sense.  That is, it explains what you are seeing, but
it certainly looks wrong.

Yes, I'll listen in to the discussion on the libtool list...
