I was thinking about this a little further and I'd prefer to avoid using
the SYSROOT_*PROCESS_FUNCS if at all possible. How about something like:

do_install_append_virtclass-native() {
	create_wrapper ${SYSROOT_DESTDIR}/${STAGING_DIR_HOST}/${bindir}/flex \
		M4=${STAGING_BINDIR_NATIVE}/m4
}

?

Cheers,
