This looks like a bad idea to me.  I think that override will cause
potentially surprising behaviour for folks who are trying to set
DISTRO_FEATURES_LIBC by hand.  And, as far as I can tell, this patch
won't make any functional difference since uclibc will just ignore the
features it doesn't understand.
