F35 mock w/ nosync broken?

[Richard Shaw]

I just upgraded to F35 and I'm trying to build a package via mock and I'm
getting the following error:

/usr/bin/python3: /lib64/libc.so.6: version `GLIBC_2.34' not found
(required by /var/tmp/tmp.mock.lxb87ex8/lib64/nosync.so)

Does it just need a rebuild or something?

Thanks,
Richard
