From 1421dc6d48296a9e91702743b31458d337610aa6 Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Wed, 30 May 2018 22:19:21 +1000 Subject: powerpc/kbuild: Use flags variables rather than overriding LD/CC/AS The powerpc toolchain can compile combinations of 32/64 bit and big/little endian, so it's convenient to consider, e.g., `CC -m64 -mbig-endian` To be the C compiler for the purpose of invoking it to build target artifacts. So overriding the CC variable to include these flags works for this purpose. Unfortunately that is not compatible with the way the proposed new Kconfig macro language will work. After previous patches in this series, these flags can be carefully passed in using flags instead.
