Add support for FreeBSD PowerPC Big/Little Endian

[lenoil98]

Support powerpc64 on FreeBSD big/little endian

[matthiasblaesing]

Please create lib/native/freebsd-ppc64.jar and lib/native/freebsd-ppc64le.jar by copying lib/native/out-of-date.jar. The build system expects correctly named jars in the lib/native folder for all "supported" architectures. The jars can be empty, but they must be present.

[matthiasblaesing]

@lenoil98 please reread my request. The empty jar need to be empty jars, not empty files. Please copy the file lib/native/out-of-date.jar to the new files. Please squash the then four commits into a single one.

@lenoil98 I used my PR for merging to integrate build fixes for Ubuntu first and squash your changes into a single commit. You are still listed as the author of the change.
