This should be _below_ the line
include $(srctree)/arch/$(SRCARCH)/Makefile
, together with the other users of cc-option, else it detects the features of
the host compiler instead of the cross-compiler when cross-compiling:
cc1: error: unrecognized command line option "-Werror=implicit-int"
cc1: error: unrecognized command line option "-Werror=strict-prototypes"
