What i did come up with was the attached, fwiw.
I did not (yet) look at how to distinguish dg-do modes, in order to get
the output_file extension right.

This works for me for
$ head -n 4 gcc/testsuite/gfortran.dg/warnings_are_errors_1.f 
! { dg-do compile }
! { dg-options " -Werror" }
! { dg-final { output-exists-not } }
! PR fortran/21061

but i take it there is a more elegant way to do this.
