I'd be nice if people could just specify CHECK and CHECKFLAGS to run
their favorite checker, but currently CHECKFLAGS seems hardwired for
running sparse. So something liike

make C=1 CHECK="scripts/checkpatch.pl" CHECKFLAGS="--quiet --file"

fails when checkpatch is passed lots of arguments like -D__linux__
-Dlinux -D__STDC__ . A little shell wrapper to grab the last argument
in that long list is a workaround, but perhaps CHECKFLAGS should be
made less sparse-specific?
