Makefile: Use cgcc rather than sparse in the check target

cgcc is the recommended way to run sparse, since it provides
many -Defines suitable for the given gcc platform. Using an
"cgcc -no-compile" command runs sparse, with all the platform
specific definitions provided by cgcc, without also invoking
gcc.
