[PATCH v2 06/10] don't run sparse{c,i} tests when sparse-llvm is disabled

Hi Chris,

I decided to have a quick attempt at one of the different approaches
to this patch that I mentioned this afternoon. So, although I have
labelled this as 'v2', its really an alternative to the 'v1' patch.

Note that I renamed sparse{c,i} to sparse{c,i}-in. It may have been
better to name then sparse{c,i}.sh, since they are not really templates
to be 'processed' to create a build product. dunno.

The Makefile changes were done in a hurry ... (I was more interested in
the test-suite changes.)

I'm not sure if this approach is any better ... what do you think?
Any other ideas?

ATB,
Ramsay Jones
