Could you try the following diff? I'll cook a proper patch and description later, but for now: --- a/tools/build/Makefile +++ b/tools/build/Makefile @@ -44,4 +44,4 @@ ifneq ($(wildcard $(TMP_O)),) endif $(OUTPUT)fixdep: $(srctree)/tools/build/fixdep.c - $(QUIET_CC)$(HOSTCC) $(KBUILD_HOSTLDFLAGS) -o $@ $< + $(QUIET_CC)$(HOSTCC) $(HOSTCFLAGS) $(KBUILD_HOSTLDFLAGS) -o $@ $<
