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.

this patch does not seem correct to me. It should be using GLRO_dl_debug_mask instead here
