musl: update to 1.1.24 + matching crosstoolchain updates
https://github.com/void-linux/void-packages/pull/15655

Description:
Updating the crosstoolchains as there have been header changes.

This also adds two backports from current musl git master, which fix some compatibility issues with glibc headers on powerpc(64) which should allow us to greatly reduce the musl-specific patches we have in the tree.

TODO/ongoing:

- [x] test crosstoolchain builds
