I've looked at this a little today.  I remember from writing this that
I thought we would try to find the spec file where the -L options
point; there is a good reason for this.  And in fact there is code in
jvspec.c to do this.  Also, the Makefile passes a -L for the current
directory to gcj.  So I wonder why this isn't working.  That's what
I'm going to look at next.
