250# @FUNCTION: econf_build
251# @USAGE: [econf flags]
252# @DESCRIPTION:
253# Sometimes we need to locally build up some tools to run on CBUILD because
254# the package has helper utils which are compiled+executed when compiling.
255# This won't work when cross-compiling as the CHOST is set to a target which
256# we cannot natively execute.
257#
258# For example, the python package will build up a local python binary using
259# a portable build system (configure+make), but then use that binary to run
260# local python scripts to build up other components of the overall python.
261# We cannot rely on the python binary in $PATH as that often times will be
262# a different version, or not even installed in the first place. Instead,
263# we compile the code in a different directory to run on CBUILD, and then
264# use that binary when compiling the main package to run on CHOST.
265#
266# For example, with newer EAPIs, you'd do something like:
267# @CODE
268# src_configure() {
269# ECONF_SOURCE=${S}
270# if tc-is-cross-compiler ; then
