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