		248	# @FUNCTION: econf_build
		249	# @USAGE: [econf flags]
		250	# @DESCRIPTION:
		251	# Sometimes we need to locally build up some tools to run on CBUILD because
		252	# the package has helper utils which are compiled+executed when compiling.
		253	# This won't work when cross-compiling as the CHOST is set to a target which
		254	# we cannot natively execute.
		255	#
		256	# For example, the python package will build up a local python binary using
		257	# a portable build system (configure+make), but then use that binary to run
		258	# local python scripts to build up other components of the overall python.
		259	# We cannot rely on the python binary in $PATH as that often times will be
		260	# a different version, or not even installed in the first place. Instead,
		261	# we compile the code in a different directory to run on CBUILD, and then
		262	# use that binary when compiling the main package to run on CHOST.
		263	#
		264	# For example, with newer EAPIs, you'd do something like:
		265	# @CODE
		266	# src_configure() {
		267	# ECONF_SOURCE=${S}
		268	# if tc-is-cross-compiler ; then
		269	# mkdir "${WORKDIR}"/${CBUILD}
		270	# pushd "${WORKDIR}"/${CBUILD} >/dev/null
		271	# econf_build --disable-some-unused-stuff
		272	# popd >/dev/null
		273	# fi
		274	# ... normal build paths ...
		275	# }
		276	# src_compile() {
		277	# if tc-is-cross-compiler ; then
		278	# pushd "${WORKDIR}"/${CBUILD} >/dev/null
		279	# emake one-or-two-build-tools
		280	# ln/mv build-tools to normal build paths in ${S}/
		281	# popd >/dev/null
		282	# fi
		283	# ... normal build paths ...
