First, I actually wonder why it only lists "finclude" and not the full
pathname.
I think the problem is that gfortran (the driver) passes something like
-fintrinsic-modules-path
/$PREFIX/lib64/gcc/x86_64-unknown-linux-gnu/4.8.0/finclude
to the actual compiler (f951).
That directory only exists if the compiler is installed but not if one
runs the test suite without installing it. I wonder how the OpenMP tests
handle it - there one needs the files from that directory. (It currently
contains the following files: omp_lib.f90 omp_lib.h omp_lib_kinds.mod
omp_lib.mod.) Answer: Theose seemingly include "$BUILD/$triplet/libgomp"
in the -I path, which also contain those files. (That probably clashes
with "use, intrinsic :: omp_lib", but that shouldn't matter.)
I am not sure whether it is the best solution, but one possibility would
be to ignore -fintrinsic-modules-path for the warning. (That assumes
that the warning is (almost) never needed for an installed compiler.)
