[fedora-java] decoupling libgcj from gcc.src.rpm

[Anthony Green]

Here's what a libgcj source RPM could look like (using FC5)...

http://people.redhat.com/green/libgcj-4.1.1-1.fc5.src.rpm 

This source RPM builds, so feel free to try it.

You'll see that the SOURCES directory contains a script called
libgcj-copy-source.sh.   This script generates the libgcj source tarball
from portions of the prepped gcc sources.

Using a libgcj source RPM like this means we can easily add our own
patches, rebuild and deploy on a schedule that is independent from the
gcc update schedule.

I'm going to have sporadic email access for the next 10 days or so.  I
just wanted to get this out for comment before I take off.

Thanks,

AG
