Notifying maintainers:
@bashu for port sketchybar.

This appears to be installing a universal binary even when that was not requested. It needs to install only for the architectures MacPorts tells it to.

[tsujp]

Unsure why, will have a look.

@ryandesign still unsure but I see a lot of other ports with the same (pnpm, yabai, and so forth).

[reneeotten]

If you look at the makefile you will see that the default target all refers to universal so that's the reason. There are other targets like x86 and arm64 which you should use depending on which systems it's building for.

[reneeotten]

with the commit I added it will build only for the requested architecture (i.e., arm64 or x86_64). I am not completely sure about the correct syntax for a universal build, and cannot test this locally I think... @ryandesign would. you mind taking a quick look before we merge this?
