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

yaboot: restrict archs so it's not available for ppc64le, yaboot-bin: remove
https://github.com/void-linux/void-packages/pull/15845

Description:
I've tested this and the compiled version can boot off ext2 and stuff no problem. So we should be able to easily drop the -bin version, which is broken in its own ways anyway.
