Automake bug fixed

Hello M4 patches,

As per <http://thread.gmane.org/gmane.comp.sysutils.automake.bugs/3989>,
this bug has been fixed in Automake's CVS.  So once you may assume that,
you can simplify Makefile.am as in the patch below.  Of course it
doesn't hurt to keep clean-local-src for a while, either.

Cheers,
Ralf

	* Makefile.am (clean-local-src): Not needed any more with
	newest Automake.
	(clean-local): Adjust.
