Yep.  I would not be too surprised if libtool needed to be taught the
way SUSE does multilibbing.  :-/

But let's not come to early conclusions.  Fact is I don't know yet what
happens on his machine.

ACK.

I coult get rid of those by using the setarch tool and the trivial patch
below:

$ setarch i386 ../cln/configure -C 'CFLAGS=-m32 -g -O2' \
        'CXXFLAGS=-m32 -g -O2' LDFLAGS=-m32
$ setarch i386 make
$ setarch i386 make check

I don't know how to deal with them more proper than that (if that's
unproper in any way).  This got me a libcln that passes `make check',
albeit now without gmp (merely because I don't have the 32bit libgmp
installed).

Ralf
