The distclean target uses the DL_DIR variable, which is derived from
BR2_DL_DIR, which can come from either the environment... or the
configuration file. So, the BR2_DL_DIR from the configuration will be
ignored. I'm not sure what the consequence is, but it's worth thinking
about this.

Also, what is the rationale for having just "distclean" and not "clean"
in noconfig_targets ? The fact that "distclean" remove the
configuration, and as such "helps" in solving configuration issues ?

Thanks,

Thomas
