I don't like this. Any process that starts during this time will fail
because the .db is missing.
The right way is to find everything and merge into the master.
This is how it should work:
DB=`gcj-dbtool -p %{_libdir}`
(cd $DB.d; ls . | xargs gcj-dbtool -m $DB)
If we expect problems with command line lengths I'll fix gcj-dbtool to
take the list from stdin.
