description:
NetBSD's very clever kernel build system can make more than one
kernel per config file and the resulting kernel need not be named
"netbsd"; therefore paw through the config file after the kernel
builds are done, find them all, and put them where they belong per
release(7). This all done with some clever awk/sh scripting, from
PR 7180 by David Forbes.
