You're using 2.6.10?
When I played with sparse on m68k (cross-compile environment), I had to make
some modifications to arch/m68k/Makefile, to pass a few additional flags to
sparse in case of cross-compilation. Later these changes were moved to the main
Makefile, since they were valid for all architectures if cross-compilation was
involved.
So I suggest to take a look at CHECKFLAGS in the main Makefile of the latest
version (2.6.11-rc5) first, and see whether it works there.
