[fedora-java] proposed rebuild-gcj-db patch

[Tom Tromey]

We've had a problem on multiarch hosts where the gcj shared library
caches weren't being updated properly, causing programs to run
interpreted instead.

This patch works around the problem by looping over all the databases
it can find.

Comments?  I'd particularly like to hear from Tom (Fitzsimmons), and
Gary...
