in multilib.conf if we do
RECIPE_SYSROOT = "${WORKDIR}/${MLPREFIX}recipe-sysroot"
RECIPE_SYSROOT_class-native = "${WORKDIR}/recipe-sysroot"
might be better, since cross etc might still need it to differentiate
multilibs
other option could be to vardepexclude it for native recipes
I was also wondering if the defaults in bitbake.conf should use
MLPREFIX unconditionally and be removed from here.
