fix for the version of the problem in comments #4 and #5

Fixes the problem.  Bootstraps and regtests OK.

How do I write a testcase to exercise this?

dg-additional-sources is not sufficient is it?  That is does it generate:

gfortran source1.f90 source2.f90

or 

gfortran -c source1.f90 -o source1.o
gfortran source2.f90 source1.0

??

The second is what is needed.
