Building libgcj without optimization

Maybe not. Since libgcj is a target library, I think things like
GCJFLAGS will always be set when configuring it (this happens via the
top-level Makefile). And I think we'd like the setting from configure
to end up in the Makefile by default.

My standard build script does this from the top level.
 make CXXFLAGS=-g GCJFLAGS=-g
This works for me. And since this affects the Makefile, future builds
in the libjava build directory pick up the -g automatically.
