Patch: for 3.1: gcj --resource

[Tom Tromey]

This patch changes gcj -R to gcj --resource.
See earlier threads for infomration on why this is necessary.

I've tested this on x86 RHL 6.2.

Ok to commit?  (I would just commit it, except it now includes a
change to gcc.c, so requires re-approval.)

Once this goes in I'll also update the appropriate web pages.
