ldconfig-native-2.12.1: newer recipe with eglibc sources
This fixes [YOCTO #780] Handle the input/output data with different endian-ness correctly Also fix the definition of LD_SO for cross environment And remove the older 2.5 version of ldconfig-native recipe (From OE-Core rev: 694db055f3729662e0e0193a31f2098be599877f) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> Signed-off-by: Nitin A Kamble <nitin.a.kamble@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
