setup.py renames xflux64/32 whenever it runs

[daTokenizer]

so the first time you run it it's ok, then it will forever fail for not finding the file.

That would cause to break the further install process, when there exists no xlux32 or xflux64 binary!

It would just pass... (haven't tested it).

I created a new PR where the binary will be copied instead of renamed.
