| |
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.
