gc-additional-sources is not a problem, that is the solution if you need
Fortran modules inter-TU and can do a link test, see e.g.
libgomp/testsuite/libgomp.fortran/declare-simd-{2,3}.f90 for one way how to
do that. With gc-additional-sources one command line of the compiler driver
compiles both source files, it is a single test from dejagnu POV, so
necessarily run together.
But there are some tests that want to have other TU modules and want to be
dg-do compile only, currently this uses a keep-modules hack which creates
inter-test dependencies. So we need something different.
