The problem is that ENABLE_SHARED_LIBGCC was not being defined when building
java/jvspec.o, resulting in gcj's link command using -lgcc when it should have
been using -lgcc_s.
This patch seems to fix it. Not that I removed $(OUTPUT_OPTION), since
cp/Make-lang.in doesn't use it and I can't figure out what it would be for.
Okay to commit?
