Machine: amd64
>Description:
A GENERIC kernel without wscons components fails to link.
>How-To-Repeat:
1. Create a kernel configuration:

# cat << EOF > TEST
include	"arch/amd64/conf/GENERIC"

ident		"TEST 2017-06-18 08:18:56 UTC"

wsbell* at spkr? mux 1

no wsbell*
no wsmouse*
no wsdisplay*
no wskbd
no pseudo-device wsmux
EOF
#

2. Try to build the kernel


# ./build.sh -T /build/netbsd-local/tools/x86_64/amd64 \
_ -D /build/netbsd-local/dest/amd64 \
_ -O /build/netbsd-local/obj/amd64 \
_ -R /build/netbsd-local/release \
_ -V RELEASEMACHINEDIR=amd64 -V MKKDEBUG=yes \
_ -U -u -x -m amd64 -j1 kernel=TEST
#
