Patchwork [CONSOLIDATED,PULL,14/22] default-distrovars: Define DISTRO_FEATURES_LIBC for uclibc

From: Khem Raj <raj.khem@gmail.com>

Defaults are for eglibc therefore we define it with an
override for uclibc

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.

Agreed. If this really is an issue we could do something like:

DEFAULTLIBFEATURES = "xxx"
DEFAULTLIBFEATURES_libc-uclibc = "yyy"
DISTRO_FEATURES_LIBC ?= "${DEFAULTLIBCFEATURES}"

Cheers,

I think its ok to drop it since OE-core is reference set of features and
let users redefine them if need be.
