RFH: trouble getting gfortran to build multilib'ed

[Steven Bosscher <stevenb at suse dot de>]

Hi,

I'm trying to make libgfortran multilib'ed.  Configuring seems to work,
but I keep running into the following problem:

This is on amd64 configured with --enable-multilib and the attached
patch applied.  As you can see, I've mostly just copied over things
from libstdc++v3, where things always works just fine.  But apparently
I need something extra, and my understanding of auto* is below zero :-/

I've been stuck on this for almost a day now and I still don't know
what/where the problem is.  Perhaps some build system hero can help
me out here?

Gr.
Steven
