When building FreeBSD the makefiles invoke find with various flags such as `-s` that aren't supported in the native /usr/bin/find. To fix this I build the FreeBSD version of find and use that when crossbuilding. Inserting lots if #ifdefs in the code is rather ugly but I don't see a better solution.
