It turns out that Sun's java command handles this in a strange way; it
sets LD_LIBRARY_PATH then re-exec's itself.  I'm going to relocate the
LD_LIBRARY_PATH setting code in this patch to a "java" wrapper binary in
java-gcj-compat that exec's gij.

While testing this I found two more java.library.path bugs:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23761

and

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23762

I'll be submitting fixes for these today.
