System: NetBSD spacekaeru 4.99.1
Architecture: i386
Machine: i386
>Description:
	src/sys/arch/i386/stand/boot/Makefile.boot has:

		cleandir distclean: cleanlibdir

		cleanlibdir:
			-rm -rf lib

	this "rm -rf" should be serialized with eg. cleandirkernlib target
	in libkern/Makefile.inc.  otherwise, with make -j, it can remove the
	directory and its contents while other instance of make is working
	under it.  in the case of nfs, it causes ESTALE.
