Subject: [PATCH 1/4] [-next] Makefile: Do not call cc-option before including the arch's Makefile

On architectures that setup CROSS_COMPILE in their arch/*/Makefile
(blackfin, h8300, m68k, mips, parisc, score, sh, tile, unicore32, xtensa),
cc-option may check against the wrong compiler, causing errors like

cc1: error: unrecognized command line option "-fno-ipa-cp-clone"

if the host gcc supports -fno-ipa-cp-clone, while the cross compiler
doesn't support that option.

Move the CONFIG_READABLE_ASM section below the inclusion of the arch's
Makefile to fix this.
