There is a new pull request by Johnnynator against master on the void-packages repository

https://github.com/Johnnynator/void-packages automake
https://github.com/void-linux/void-packages/pull/22331

automake: use makejobs instead of -j$(nproc)
@Piraty, was there any reason that nproc was used?

A patch file from https://github.com/void-linux/void-packages/pull/22331.patch is attached
