New issue by dkwo on void-packages repository

https://github.com/void-linux/void-packages/issues/29632

Description:
Has a `musl` update been planned?
My reason for asking is I'm trying to build [flint](http://flintlib.org) and it throws me an error `unknown type name 'cpu_set_t'`, while I noticed Alpine Linux packages it.
Otherwise, does anyone understand what should be patched in our `musl` to build it?

Thanks.
