Change 131189 by jb at jb_freebsd1 on 2007/12/19 01:07:35

	Add a knob to allow just the kernels to be (re)built during
	a "make universe". This is intended for use with NOCLEAN when
	trying to find a fix for the "chase the variable type tango".
	Having to trudge through a buildworld that you know has already
	succeeded is a pain in the bottom.
