eglibc: Make it configurable by tuning eglibc options
* Look for disabled features in DISTRO_FEATURES and disable them while building eglibc * By default all features are built * One can disable a feature by specifying DISTRO_FEATURES += "noinet6 nobsd ...." e.g. Signed-off-by: Khem Raj <raj.khem@gmail.com>
