Support out-of-tree kmod build on FreeBSD
If srcdir != builddir, pass down MAKEOBJDIR to the FreeBSD make to
support out-of-tree builds.
Also allow passing all the gmake options that FreeBSD make understands
to support useful flags like -k, -n, -q etc, and detect the number of
CPUs if -j was specified without an argument.
