The patch would help only is imake is also changed so that it doesn't
hardcode the architecture specific flags at the compile time.

In case if anyone cares, here's the script my $IMAKECPP points to.  It's
a hack, but it gives an idea what it takes to override the flags
supplied by imake.

#!/bin/sh

# cpp wrapper to fix flags passed by imake to cpp.
# If compilation is targeted for i386, replace all references to x86_64
# with i386 to help Autoconf generated configure find correct path to
# X11 libraries.
# Set IMAKECPP to the full patch to this script.
# Written and placed in public domain by Pavel Roskin, 2005.

# Heuristics to check if i386 is targeted
env32=

case $CC in
*-m32*) env32=1;;
esac

case $CFLAGS in
*-m32*) env32=1;;
esac

case `uname -i` in
i386) env32=1;;
esac

# i386 not targeted - no flag replacement
if [ -z "$env32" ]; then
        exec ${CC-cc} -E "$@"
fi

# This could be greatly simplified with bash arrays, but the only
# portable array is the shell arguments.
first=1
for i in x ${1+"$@"}; do
        if [ "$first" ]; then
                set x
                first=
                continue
        fi
        shift
        set x ${1+"$@"} "`echo $i | sed 's/x86_64/i386/;s/amd64/i386/'`"
done
shift

exec ${CC-cc} -m32 -E ${1+"$@"}
