This is exactly the kind of thing I did not want to see
MUTLILIB_SCRIPTS used for. Its now being proposed everywhere you have
an issue with conflicting files without consideration about what
actually makes sense.

What might make more sense here is only to build os-release for the
main namespace and not any of the multilibs. It could RPROVIDE if
necessary.
