[fedora-java] Enhanced aot-compile script

[Andrew Haley]

The way this traditionally works in UNIX is by using `make'.

For example, to rebuild the mail database you simply go to /etc/mail
and type

    make

which does whatever is necessary.

Why not do it this way with gcj's dependencies?  Just go into
/var/lib/gcj<blah> and run make?  The makefile can then do everything
that is necessary, using make's dependency analysis.
