Subject: [PATCH] Implement an idea from Sam Leffler: 	make KERNFAST=blah
 buildkernel is now a short cut for 	make KERNCONF=blah -DKERNFAST
 buildkernel

This change works for all kernel config files not named "1".  I did
that to make sure that
	make -DKERNFAST buildkernel
remains the same as
	make -DKERNFAST KERNCONF=GENERIC buildkernel
rather than trying to build and configure "1".  I've never seen a
kernel config file named "1," so I think this is a good compromise.
