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 ${0##*/} -m32 -B/usr/lib32 -isystem/usr/include/i386 "$_at_"

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
