All FreeBSD systems on which Arla is likely to work have the
module-build infrastructure, although it works somewhat differently in
4.x (now approaching EOL) than in 5+.

There needs to be some configure infrastructure to set KERNBUILDDIR to
an appropriate place, if the user is not using the GENERIC kernel.
