Reproducibility issue in 0.17.5

[DFINITYManu]

After 0.16.20 which was perfectly reproducible no matter the path to the project including ring, 0.17.5 has reproducibility issues.

What you are looking at is the same program built under directories metrics-proxy and petrics-mroxy, but with the RUSTFLAGS='--remap-path-prefix=/home/manuel/src/petrics-mroxy=/home/manuel/src/metrics-proxy' which ensures both should be identical -- and they are, so long as the ring version is 0.16.20, but not with 0.17.5.

We have mitigated using the CFLAGS trick mentioned in #715 but we would prefer not to have to do this.

Thanks in advance!

Closing as a duplicate of #715. I don't know why/how 0.16.20 didn't have the same issue, BTW.

I found the reason why 0.16.20 here was working... the CFLAGS trick was being used and I did not notice it. Thanks.
