Sure.  And then people will still see the conflict resolution on update as
we have libgcj_bc1-gcc48 installed and libgcj_bc1 and libgcj_bc1-gcc[56](?)
as update candidates.  Avoiding that needs to mess with gcc itself providing
obsoletes/provides (not sth I would suggest).

So admit failure and accept the conflict dialogue.

There's a gcc48 update for SLE12 pending (not yet submitted).
