Remove Java support (both in terms of the JAVA option and everything
associated with it as well as java from CATEGORIES) from this port.
Technically GCC 4.8 only went end-of-life upstream in June 2015, alas
GCC 4.9 and GCC 5 are well established by now and also provide support
for Java (GCJ/libgcj), and this change simplifies this port significantly
and speeds up the build.
In addition to the expected changes to Makefile, pkg-plist, and pkg-descr,
this also removes files/java-patch-hier.
Welcome GCC 4.8! For the next couple of months this is going to be
a rougher ride, as this release series -- just branched off GCC 4.7
-- is going to see a lot of active and often invasive development.
This port is for early exposure and not production use at all.
Feature safe: yes
