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