testclean

[Philip.Blundell@pobox.com]

At the moment it's awkward to re-run `make check' because Make only tries to 
build everything once.  This can be infuriating if, say, you realise too late
that you wanted to capture the test output, or you want to run the tests 
several times under different kernel versions. 

This patch adds a new target, `make testclean', which removes all the test 
cases and their output files from the build tree so that `make check' will 
perform all the tests anew.  Does it look OK?

p.

	* Makefile (tests-clean): New target, removes test cases and 
	associated output files.
	* Makerules (do-tests-clean): New rule to support the above.
	* Rules (subdir_testclean): Likewise.
