I found the culprit via git bisect: 380bccf

• gcc is missing from build-plugin #581

Some extra information about the different GCC versions involved:

$ gcc --version  # host
Apple clang version 16.0.0 (clang-1600.0.26.6)
Target: arm64-apple-darwin24.1.0
Thread model: posix

This is free software; see the source for copying conditions.  There is NO

Interestingly, the build succeeds from within the devshell:

If I remove gcc from the flake, the build also succeeds:
