This one should be better.

On the sparse topic. Do you see anything against
introducing CHECKFLAGS?
CHECKFLAGS would be assigned the sparse specific flags in
arch/*/Makefile.

I see no reason to introduce EXTRA_CHECKFLAGS, CHECKFLAGS_$(F*)
as known from CFLAGS, AFLAGS. But I like the split into CHECKFLAGS.
That should allow me to do:
make CHECK=my_hacked_sparse C=2
