257# @FUNCTION: econf_build
258# @USAGE: [econf flags]
259# @DESCRIPTION:
260# Sometimes we need to locally build up some tools to run on CBUILD because
261# the package has helper utils which are compiled+executed when compiling.
262# This won't work when cross-compiling as the CHOST is set to a target which
263# we cannot natively execute.
264#
265# For example, the python package will build up a local python binary using
266# a portable build system (configure+make), but then use that binary to run
267# local python scripts to build up other components of the overall python.
268# We cannot rely on the python binary in $PATH as that often times will be
269# a different version, or not even installed in the first place. Instead,
270# we compile the code in a different directory to run on CBUILD, and then
271# use that binary when compiling the main package to run on CHOST.
272#
273# For example, with newer EAPIs, you'd do something like:
274# @CODE
275# src_configure() {
276# ECONF_SOURCE=${S}
