Comment:
> The inability to rebuild a package does affect me when I'm trying to recompile parts of Void for reproducibility (and/or local testing/hosting), and I believe it's useful to have a current set of buildable and re-buildable distribution for testing infrastructure like toolchain upgrades.

Definitely, but if the patches are off by a few lines (like here), the packages will still be build-able. The reason why this package didn't build for you was the whitespace issue that was triggered by us disabling loose whitespace matching in patch (we now use `patch` without `-l`).

Try applying this minimal patch and the package will build fine without the rest of the changes.
