[Patch, Fortran] PR 49265 - allow :: for "procedure :: list"

[Janus Weil]

Hi Tobias,

> Fortran 2008 now also allows the "::" in module interfaces: "[module]
> procedure [::] procedure-name-list"
>
> The bug is also a sign for bad quality assurance as we previously only fixed
> the issue for "module procedure" and not also for "procedure".
>
> Build and regtested on x86-64-linux.
> OK for the trunk?

certainly ok. Thanks for the fix!

Cheers,
Janus
