Comment:
I hate rust toolchain for doing as much as possible to make troubleshooting hard.
If one conditionally state[1][2] ABI=32, it'll likely work. Usually it is just patch. With cargo, one need to publish full fixed source in git repository online, then patch dependency tree[3], if available.
Mentioned gmp-src/configure dissapears after build fails, luckily it is materialized in repo, not generated during build.

If you don't file like patching, just mark `archs="~i686*" # aggresive cpu detection`.

In any case, optionally report upstream.
