The test suite doesn't depend on anything that the main code doesn't
already require. So you should be able to just run 'make check' and
it'll compile & run the tests.

Of course reality may differ from theory :-)

I strongly expect that the QEMU driver has a large number of Linux-isms
in it. That said, I also expect all the Linux-isms to be solveable. So
my recommendation is probably to enable it, then insert enough #ifdef's
to get just the basics compiling. Then post the #ifdef details to the
list so we can figure out an optimal way to handle the Linux-isms long
term, and make suggestions on how to provide BSD alternative impls.

The kernel-headers check is an example of a Linux-ism we should look
to solve.
