I agree with koen, when distro wants to keep all default libc-* but
alter other DISTRO_FEATURES it has to list all libc-* in it's own
config.
IMHO DISTRO_FEATURES_EGLIBC had wrong only suffix as it's not _EGLIBC
specific,
DISTRO_FEATURES_LIBC or proposed DISTRO_LIBC_FEATURES will allow
distributions to override it like this:
DISTRO_FEATURES = "foo bar ${DISTRO_FEATURES_LIBC}" which is much better
then 6 lines of libc-* features which need to resync when someone adds
new feature with new *libc version.
