Try adding this to the end of the main Makefile:

+$(info LDFLAGS_BUILD_ID = $(LDFLAGS_BUILD_ID))
+$(info KBUILD_ARFLAGS = $(KBUILD_ARFLAGS))
+$(info KBUILD_CFLAGS = $(KBUILD_CFLAGS))
+$(info KBUILD_AFLAGS = $(KBUILD_AFLAGS))
+$(info KBUILD_CPPFLAGS = $(KBUILD_CPPFLAGS))
+$(info REALMODE_CFLAGS = $(REALMODE_CFLAGS))
+
 endif  # skip-makefile

Record what you see.  Then apply my patches and run your build again
(actually, run it twice and look at the 2nd time, just to be sure).  I
think you'll see slightly different spacing in the flags for the two
runs.  I don't think this is terribly important, though.
