Subject: [PATCH] Adding compiler options for building fat binaries on MacOS.

Originally they were written in `configure.ac` for `darwin9`.
Unfortunately, this doesn't work on Github workers:
- clang: error: no such file or directory: 'ppc'
- clang: error: no such file or directory: 'x86_64'

Maybe that's because the target on macos-runner is `x86_64-apple-darwin21.6.0`.
