[cp-patches] Patch: FYI: build fixlet for gcj

[Tom Tromey]

I'm checking this in.

If we remove a .java file from Classpath, the gcj build will fail
because the generated dependencies will tell it to find the missing
file (and it will try to rebuild it and then fail).

This patch fixes the problem, using the same technique used for C.
Namely, we emit a phone "foo.java:" target for all the source files,
so that if they are missing we don't try to build them.
