There's a merged pull request on the void-packages repository

New package: zn_poly-0.9.2
https://github.com/void-linux/void-packages/pull/33969

Description:
Dependency for sage. I compiled sage-9.4 using this.

I run tuning in my box, once in 64 bit mode, once in 32 bit mode, and hardcoded the resulting tuning files. Won't be optimal for all cpus, particularly for non-x86, but it seems a fair solution and avoids running tuning each time. Tuning won't work for cross compiling anyway.
