[Bug fortran/31588] New: gfortran should be able to output Makefile dependencies with -M* options

["fxcoudert at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

gcc has various -M options to create Makefile dependencies for automatic
dependency tracking, which is very nice for compilation of large projects.
gfortran should be able to do the same. Here are examples with g95:

$ cat a.f90 
module foo
  integer, parameter :: bar = 42
end module foo
$ g95 -M a.f90     
a.o foo.mod: a.f90
$ cat a.F90
include "foo.inc"

module foo
  integer, parameter :: bar = 42
end module foo
$ g95 -M a.F90
a.o foo.mod: a.F90 foo.inc
