The existing libclone.h already tries to define these for arches that
need them. I certainly believe that there are distributions which
are still funky, but let's understand why.
Do you have a machine of your own on which you needed this? Can you
remove this bit and let me know what happens?

What on earth are you using clone64 and unshare64 for? They don't
actually exist, and you certainly don't need them for network
namespaces.

Again, you shouldn't need the above.
