I think this is the wrong way to go. If you add #ifdefs to the sources,
you have to make the binaries target-specific. Currently each test
binary can work for each target architecture. With #ifdefs, that's not
possible anymore. So please don't do that.

If you want to make the tests more flexible for configuration, please
use QOM instead to check whether the devices are available or not.
