@bwoodsend,@wangling12, please take a look.

This seems to break bootloader compilation inloongarch64/alpine:3.21 container, becausectx.env.DEST_CPU that is passed asmachine argument topyi_machine (here) seems to be set to an empty list instead of an architecture identifier. This probably comes from waf's failure to identify the target arch from compiler defines/macros; presumably same happens with SunWay, which is whyplatform.machine() is checked first (at the cost of losing ability to cross-compile bootloader for these platforms).

Yup,loongarch64 detection first needs to be added to waflib. I'm working on that.

What exactly is it that you are trying to fix, though? I.e., what is wrong with the current approach for these two platforms?

Note that PyInstaller uses a vendored copy ofwaflib, so you will need to add detection forloongarch to
