[Bug fortran/18297] New: gfortran : file opening fails if only read access

["mimo2 at free dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

using a gfortran build as of today (but this was true also for older versions)
open(unit=xx, file=filename, status='old') crashes on linux with
Fortran runtime error: Permission denied
when we only have read access to the file filename (but works if write access)
