The "unknown" part should be irrelevant. My point was that you are
telling the autoconf/automake configure system (and maybe libtool too)
that you want to build an x86_64 project, but then with the -m32
compiler flag, you tell the compiler that you want to generate i386
code.

So I suggest trying to tell configure to build a 32-bit project by
setting host to "i386-unknown-linux-gnu", along with specifying your
-m32 flag to the compiler. See if that helps out at all.
