This has been fixed in automake CVS some time ago.  Maybe the fix will be
carried over to the 1.8 release branch.

This is the change that has been added to automake:

2004-05-23  Alexandre Duret-Lutz  <adl@gnu.org>

	* lib/am/multilib.am: Add $(MAKE) comments to multido and
	multiclean lines, to enable parallel make.  Based on a patch
	by Alexandre Oliva applied to newlib on 2003-10-15.
