Definitely. For -static you either have the choice of linking the
binary with -Wl,--whole-archive for libgcj.a (and likely other Java libs),
or spend a lot of time adding more and more objects that are really
needed, but linker doesn't pick them up.
For the distribution, we simply remove all Java *.a libraries, but it would
be a build time win if we don't have to compile them altogether.
