>Description:
	When running ``build.sh release'' with KERNEL_DIR set to "yes", the
	kernel build tries to put _all_ non-INSTALL kernels into a single
	file $DESTDIR/netbsd/kernel and you get an error.  For amd64, there
	are 4 such kernels, and here are the errors:

...
echo  netbsd | GZIP=-9\ -n XZ_OPT=-9 /build/netbsd-local/tools/x86_64/amd64/bin/nbpax  --use-compress-program /build/netbsd-local/tools/x86_64/amd64/bin/nbxz -O -w -M -N /build/netbsd-local/src_ro/etc -f /build/netbsd-local/release/amd64/binary/sets/kern-GENERIC.tar.xz

>How-To-Repeat:
	See above
>Fix:
	Fix unknown, however a mechanism needs to be defined to specify
	which kernel should be installed, and decide what to do with (or
	where to put) any other non-installed kernels.
