I don't actually know, my initial interpretation was that
these function names are part of the user ABI for the vdso,
but I never looked closely enough at how vdso works to
be sure what the actual ABI is.

If __c_kernel_clock_gettime() etc are not part of the user-facing
ABI, I think renaming them for consistency with the other
architectures would be best.
