[fedora-java] Patch to find-and-nativify

[Robin Green]

This proposed patch makes 4 changes to the find-and-nativify in 
java-1.4.2-gcj-compat-1.4.2.0-40jpp_14rh.

- Generates a database as it goes, rather than forcing the spec file
writer to write a similar script to build the db.

- Qualifies each lib with the package name, to avoid name collisions in
Provides. (Which suggests the thought that since package names _must_ be
unique by design in rpm - isn't it then sufficient to generate libs in
%{_libdir}/%{name} instead of as %{_libdir}/%{name}/full/path/to/jar ?)

- Ignores jars which are symlinks (they might not even be in the package,
and if they are, you will end up compiling them more than once.)

- You can set the SKIPTAR environment variable to skip the tar building,
for more efficient rpm builds.

I have a handy utility script to post next which assumes some of these
changes, so I will wait to see what happens to this patch first.
