# Workhorse makefile for creating ONE cross compiler

# BUILD -> HOST prebuilt
#
# NOTE: There is a bug here. We don't limit the
# PATH when building BUILD -> BUILD, which means that
# if you configure after you've once build the BUILD->BUILD
# compiler THAT one will be picked up as the compiler for itself.
# This is not so great, especially if you did a partial delete
# of the target tree.
#
# Fix this...
