Greg Lehey 4357ca882d Back out default debug kernel. The flags revert to historical behaviour.
Requested-by:	ache

Modify targets for debug kernels:  when -g was specified, make will
now build a debug kernel called kernel.debug, and create a stripped
version called kernel at the same time.  The two targets install and
install.debug are otherwise unchanged.

Requested-by:	dillon

Update man page accordingly.
