But there is a good reason to relink on ELF: uninstalled libraries and
executables get DT_RPATH entries against uninstalled libraries they depend on,
so that uninstalled programs can be executed in a test suite before installing
the libraries they depend on.  Removing (or replacing) those DT_RPATH entries
is the point of relinking.  That GCC takes care of the uninstalled paths in
some other way as well is something libtool cannot know.
