Ok, I added an --exclude option to handle this, and it's now built in
beehive as java-1.4.2-gcj-compat-1.4.2.0-40jpp_32rh so if you could
test it it would be very cool.  You should be able to drop all solib
compilation and database building stuff, sticking an aot-compile-rpm
at the end of %install, and changing the %files sections to the new
locations.

Note that for --exclude the path you must is the final installed
path of the jarfile, for example
/usr/share/eclipse/plugins/org.eclipse.ui.workbench_3.1.0.jar
(_not_ prefixed with $RPM_BUILD_ROOT).

Note also that you shouldn't need to do this for the PPC limit
(#158308) because aot-compile-rpm ought to be able to handle it.
If you do have problems then let me know as it's a bug I should
be fixing.

Also note that for optimizer failures you can build the solib
yourself into the location that aot-compile-rpm would have built
it _before_ running aot-compile-rpm.  aot-compile-rpm will generate
the database for it.

Finally, note that you can remove the %{_libdir} argument from all
the rebuild-gcj-db commands, as it's not necessary any more.

Cheers,
Gary
