[PATCH] gfortran.dg test harness for gfortran

["Billinghurst, David (CALCRTS)" <david dot billinghurst at comalco dot riotinto dot com dot au>]

Here is the minimal gfortran.dg test harness, adapted from g77.dg.
I have also christened it by copying one test from g77.dg

I propose that we delete g77.dg/strlen0.f and progressively move
the working tests from the g77 testsuite into the gfortran testsuite,
with the aim of eventually deleting the g77 testsuite.

Tested on i686-pc-cygwin

	* lib/gfortran-dg.exp: New file (adapted from g77-dg.exp)
	* gfortran.dg/dg.exp: New file (adapted from g77.dg/dg.exp)
	* gfortran.dg/strlen0.f:  Copied from g77.dg
