This broke cross-compilation using a cross-compiler that supports less compiler options than the host compiler. E.g.:
cc1: error: unrecognized command line option "-Wno-unused-but-set-variable"
Reverting commit ae6b289a37890909 ("kbuild: Set KBUILD_CFLAGS before incl. arch Makefile", which was in linux-next since next-20171124) fixes that.
BTW, this gets broken regularly, cfr. e.g. commits a1c48bb160f8368e ("Makefile: Fix unrecognized cross-compiler command line options") and bef5b54bd7bf8117 ("Fix MIPS cross-compile problem").
Gr{oetje,eeting}s,
Geert
