On architectures that setup CROSS_COMPILE in their arch/*/Makefile (arc, blackfin, m68k, mips, parisc, score, sh, tile, unicore32, xtensa), cc-option and cc-disable-warning may check against the wrong compiler, causing errors like cc1: error: unrecognized command line option "-Wno-maybe-uninitialized" if the host gcc supports a compiler option, while the cross compiler doesn't support that option. Move all logic using cc-option or cc-disable-warning below the inclusion of the arch's Makefile to fix this. Introduced by - commit e74fc973 ("Turn off -Wmaybe-uninitialized when building with -Os"), - commit 61163efa ("kbuild: LLVMLinux: Add Kbuild support for building kernel with Clang"). As -Wno-maybe-uninitialized requires a quite recent gcc (gcc 4.6.3 on Ubuntu 12.04 LTS doesn't support it), this only showed up recently (gcc 4.8.2 on Ubuntu 14.04 LTS does support it).
