Try removing and reinstalling poco. I have seen some issue with packages not getting rebuild nicely when a dependency like poco changes. And I cant really explain the linker error.

Tried removing and adding poco already before, but retried again. Doesn't help. Using -v creates a ton of output, starting and ending with

Again, it's the same on both architectures. No issues with other homebrew formulas. Using zsh as standard shell.
