[RFC] Remove pdftk and gcc-java

[Yaakov Selkowitz]

GCJ is practically dead these days, and it has been completely dropped 
from Fedora.  For that reason I didn't bother porting gcc-java to x86_64 
after seeing that work would be required to do so.

The one package in the distro which still required GCJ -- namely, pdftk 
-- actually has licensing issues:

https://lists.fedoraproject.org/pipermail/devel/2014-March/196371.html

With the recent addition of qpdf for both arches (thanks, Marco!), I 
would like to remove pdftk from the distro, and gcc-java from gcc in the 
next build.  Any objections?
