Dear maintainer,

Full buildd log:
https://buildd.debian.org/status/fetch.php?pkg=numactl&arch=riscv64&ver=2.0.14-3&stamp=1632275973&raw=0
This can be fixed by linking to libatomic on riscv64, which I've written a
patch solving the problem. I will submit it to the upstream repo soon.
Please let me know if I miss something.
Cheers,
Eric
