There was 'dim checker' before, and now also 'dim sparse'. Both do the
builds in the current directory, and do not cd to drm-intel directories,
so they can be used independent of other dim stuff.

In any case, running sparse is just a matter of having sparse in PATH,
and building using make C=1 or C=2. The former will run sparse on just
the files that need to be recompiled, the latter on everything. See also
'make help'. The helpers in dim first touch the the sources or rm the
object files, and run C=1.

Thanks.
