Revive a skeleton for bsd.kmod.mk (which will be in the make search path) that merely locates and includes sys/conf/kmod.mk.

# $FreeBSD$
# Search for kernel source tree in standard places.
Add ${.CURDIR}/../../../.. to the list of places we look for the kernel. The new moudles/sound/drivers/foo pushes us down one more level.

.for _dir in ${.CURDIR}/../.. ${.CURDIR}/../../.. ${.CURDIR}/../../../.. /sys /usr/src/sys
Do not check for existence of ${_dir}/kern/ , because for modules that set .PATH to ${.CURDIR}/[...]/kern , the "exists" expression will fail for the form exists(${.CURDIR}/[...]/kern/). This appears to be happening because make is searching for the argument to "exists" by using .PATH rather than a relative search, because .PATH and the argument match at the beginning. Additionally, make appears to consider a path that starts with ${.CURDIR} as relative, even though it expands to an absolute path. The reason that most people aren't seeing this problem is that the absolute paths of /usr/src/sys and /sys are also searched, so as long as the kernel source can be found in at least one of those places, no problems surface. This problem was inadvertently introduced on 1 December 2000, with the addition of the sysvipc modules.

Sigh. Use the correct path to bsd.conf.mk. It's times like this that I regret giving up coffee.
