Comment (by kencu):

 I don't know exactly how the `+universal` variant propagates through
 dependencies, but I would have thought that it would have worked like
 this:

 `openblas +universal` --> `gcc9 +universal` --> `libgcc +universal` -->
 `libccN +universal`

 Is there a breakdown somewhere in this chain of dependencies?
