[Patch, Fortran] specific or generic INTERFACE implies the EXTERNAL attribute (PR36325)

[Janus Weil]

Hi all,

here is the fix for PR36325, regtested on i686-pc-linux-gnu with no
failures. Since I have svn write permission now, I can commit it
myself. I just need someone to approve it.

Cheers,
Janus
