OpenJDK for PowerPC64

[Curtis Hamilton]

It's been a while, but I'll have to take a look and see if I documented the
changes I made, other than adding java to the list of the build languages in
the "Makefile".  Changing the makefile was simple, but I remember that not
every version of GCC would build GCJ.  GCC48 and GCC49 failed with internal
compiler errors.  I was able to build with GCC47 and GCC5, but there was an
issue during stage 3 of each build with libtool errors.   To get past this
error I had to make changes to the build order of the GCJ libraries.

Thanks!  Did you need to patch anything for gcc to build java, or did you
need to just tell it to build?  I remember when I started looking at it a
few years ago there were some things needed, but I can't recall what I did.
It's not difficult to add java to the port for powerpc, so if your changes
were trivial, or you had no changes, that could be a good first step for us
to add this to the ports tree.
