Subject: sparse: add make variable C to run sparse when compiling skiboot
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As this is done on the Linux kernel, one can now run sparse using
C=1 on the command line. The variable CF can be used to tune the
sparse options.
