From: Kang Kai <kai.k...@windriver.com>
Migrate configurability from oe, try to shrink minimal image size
The switch is in local.conf.sample, uncomment the line
DISTRO_FEATURES_EGLIBC = ""
and write what options you want to enable.
If want to disable locale-code charsets or locales, you have to uncomment
PACKAGE_NO_GCONV = 1
Because without this, it fails on package_do_split_gconvs in
libc-package.bbclass
