Compiled and installed on M1 Macs as arm64, recognized by some package as x86_64?

This might not be a emacs-plus issue, but I have tried all sorts of things including talking to the maintainer of the problematic package in question first: https://github.com/vedang/pdf-tools/issues/107, and I'm hoping the emacs-plus community could shed some light on the problem.

I'm having trouble of building pdf-tools for emacs-plus (both 27 and 28 tried and failed). It always complains the following before the compilation fails:

I can confirm my emacs-plus is compiled natively on a M1 MBA (macOS 11.6.6), and the resultant Emacs process sampling shows Code Type: ARM64. In addition, it seems the Emacs builds from: https://emacsformacosx.com do not suffer from the same issue, so I wonder if I've made some error in my emacs-plus installation or configuration. Any suggestion is much appreciated.

Same problem here.
