Subject: [PATCH 2/2] powerpc: replace pseries_le_defconfig with a Makefile target using merge_config

From: Cyril Bur <[email-masked]>
Date: Fri, 15 May 2015 15:47:10 +1000

Rather than continuing to maintain a copy of pseries_defconfig with enabled
CONFIG_CPU_LITTLE_ENDIAN, use the generic merge_config script and use an
le.config to enable little endian on top of pseries_defconfig without the need
for a duplicated _defconfig file.

This method will require less maintenance in the future and will ensure that
both 'defconfigs' are always in sync.
