Fix Nix macOS build

[pepyakin]

Description

For me, on macOS 10.15.7 running make would fail with errors about -iframework. This change fixes it. I assume that the name of the flag has been changed.

I haven't checked this change on a linux platform. Would appreciate if somebody did.

@purcell thoughts?

[purcell]

Yes, this fix is appropriate and good: I can reproduce the error locally, and this resolves it.

[purcell]

Actually, hold off on merging -- just a couple more things to test first.

[purcell]

Yeah, this is good to go -- thanks @pepyakin!

I have a further fix to submit which fixes compilation on Big Sur, so expect a fresh PR soon.

Just ran into this as well and was about to open a PR, but I'm glad I searched first :) Let me know if I can help test anything.

Relatedly thinking it might be nice to set up a Cachix cache, and then have a build job which populates it. This way, us Nix users downstream can mostly avoid compiling avr-gcc locally, and there would also be a specific build check to verify that changes like this one do not contain significant regressions.

P.S. See also #11181, which fixes the Nix shell for Big Sur users.

Hey all, is there anything I can do to move this and #11181 forward?
