I think it'd be much easier to use smth like /usr/include/i386/machine.
So one can shadow /usr/include/machine from cc/c++ wrapper.
#! /bin/sh
skip-path() {
local IFS=:
PATH=$(for p in $PATH; do
case $p in
$1) ;;
*) echo -n $p: ;;
esac
done)
}
skip-path "*${0%/*}"
exec ${0##*/} -m32 -B/usr/lib32 -isystem/usr/include/i386 "$@"
Tested only on simple ports like lang/python26 with no deps, e.g.
# here you should put above cc/c++ wrapper into ~/.wrap32/cc
$ (cd ~/.wrap32; for f in c++ gcc g++; do ln -s cc $f; done)
$ export PATH=$HOME/.wrap32:$PATH
$ cd lang/python26
$ make install
