[Bug fortran/36441] New: gfortran looks for .mod files in default locations before -I directories

["David at ham dot dropbear dot id dot au" <gcc-bugzilla at gcc dot gnu dot org>]

gfortran appears to pick up .mod files from default locations in preference to
directories specified by -I arguments on the command line. So, for example, if
foo.mod is in /usr/include and foo.mod is in /home/bar/somedir and the user
types:

gfortran -I/home/bar/somedir ...

then gfortran will pick up /usr/include/foo.mod . This causes particular
problems when the system gfortran distributed with the OS is, say, 4.2 and a
user has installed gfortran 4.3 since nothing the user can specify on the
command line will prevent .mod files from installed packages (generally
compiled with 4.2) being used.
