[EMBOSS] Build -m32 on 64 bit host, problems

Trying again to compile Emboss 6.3.1.  Attempting to build 32 bit
versions as most of the target machines run that, however, the compiler
is running on a 64 bit OS.

Download 6.3.1, unpack, apply 1-4 patch.  Then in top level:

export CFLAGS="-march=athlon-mp -m32"
./configure --prefix=/usr/common

which all went fine, except that:

grep m32 Makefile
CFLAGS = -march=athlon-mp -m32  -O2  -DNO_AUTH -D__amd64__

I don't see how to reconcile __amd64__ with the other flags.  Is there
some switch that can be thrown in ./configure to correct this?  Note, I
really do want the 32 bit version even on the 64 bit system, so that all
of the machines will be running exactly the same version.

Thanks,
