Remove Java support
This patch removes the Java support from gdb. gcj has not seen much
development or use for years now, and was recently removed from GCC.
This patch changes gdb to follow; in the unlikely event that there are
still users using gcj, they can continue to use an older gdb to debug.
Or, they can debug in C++ mode.
Built and regtested on x86-64 Fedora 24.
