[PATCH 1/1] eglibc: check for required distro features

[Chen Qi]

If users accidently override the DISTRO_FEATURES in local.conf,
then build failures occur for lack of libc functions.

All features in DISTRO_FEATURES_LIBC should be in DISTRO_FEATURES.
That's why this patch let the recipe inherit distro_features_check
class and set REQUIRED_DISTRO_FEATURES to "${DISTRO_FEATURES_LIBC}".
