Bug#1125262: dh-fortran: dh_fortran_* commands do not honor the debhelper -O option

[Rafael Laboissière]

Package: dh-fortran
Version: 0.62
Severity: normal

Dear Maintainer,

According to the debhelper man page:

   -O=option|bundle
       This is used by dh(1) when passing user-specified options to
       all the commands it runs. If the command supports the specified
       option or option bundle, it will take effect.  If the command
       does not support the option (or any part of an option bundle),
       it will be ignored.

Indeed, it seems that the dh_* commands, including those from 
debhelper add-on packages (like dh-octave, dh-php and dh-lisp, to name 
a few), honor the -O option.

However, this is not the case for the dh_fortran_* commands. So, please fix this.

This is particularly annoying for the plplot package. Currently, I 
have to add the following to debian/rules, in order to circumvent the 
bug:

    override_dh_fortran_lib:
            dh_fortran_lib

    override_dh_fortran_pkgconf:
            dh_fortran_pkgconf

    override_dh_fortran_cmake:
            dh_fortran_cmake

    override_dh_fortran_mod:
            dh_fortran_mod

This is necessary, because of the following rule:

    %:
            dh $@ -Scmake --with python3,ocaml --with fortran_mod --with javahelper

Best,

Rafael
