From: Kang Kai <kai.kang at windriver.com>
Migrate configurability from oe, try to shrink minimal image size
Update to get eglibc configuration options from DISTRO_FEATURES and enable them. All
the options are enabled by default.
Uncomment the line in conf/local.extended.conf to define DISTRO_FEATURES, so put
what options you want to enable there.
