Comment (by Ionic):

 Have you asked upstream about it?

 I think they only ever have considered one architecture at a time.

 Generally, I think that pkg-config files (and stuff like icu-config)
 should be handled in arch-dependent directories. Many Linux distributions,
 for instance, have a long history of supporting multi-arch (sometimes
 called multilib) stuff, splitting files into directories like
 `${prefix}/lib64` and `${prefix}/lib32` (for `x86_64` and `x86`
 architectures).

 I believe that MacPorts could do the same, but Apple-based systems are
 more powerful in the sense that they support fat binaries, which Linux
 does not. That makes things easier, but also much more complicated if
 files actually differ...
