fortran-modules does not (currently) use include-dir search path logic
to find include files.

RUNTESTFLAGS='-v -v' (for example) shows the testcase that it currently
works on, as you know.

I have removed the unwarranted warning after successful (1) toplevel
regtesting and committed it as r185688.

The second part of the "implicit cleanup-modules" would be to remove
the now superfluous manual cleanup-modules calls.

Something like this, ran in the sourcedir removes those:
(cd gcc/testsuite && grep -rl "cleanup-modules" * | \
 egrep -v "(\.exp|ChangeLog|\.svn|gfortran.dg/(class_4(a|b|c|5a).f03|binding_label_tests_1(0|1|1_main|3|3_main).f03|test_common_binding_labels_(2|2_main|3|3_main).f03|whole_file_(28|29|30|31).f90))" | \
 while read f;do \
   sed -i -e ':crap' -e '/cleanup-modules/d' -e '/^\n*$/{$d;N;bcrap' -e '}' $f; \
 done)

1) Completely unrelated bug in the testsuite showed up as 2 regressions
in the above testing. I have filed that as gcc.gnu.org/PR52665
