--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> --- E.g. one major problem with doing -rpath behind the scenes is that it totally breaks GCC's relocatability. One should be able to move the gcc install directories into other place and it should still work (say from the /usr/local paths to /tmp/blah/foobar).
