Homebrew formula broken since 0.8.10

[cameel]

Description

We maintain a custom Homebrew formula to build Solidity on macOS: solidity.rb. Since at least 0.8.10 we've been having various build issues in CI so the formula does not pass tests. It may or may not be broken on real systems. Solving these requires some debugging, preferably by someone with a mac.

Fixing this is not urgent since this affects only 0.8.x and for that version there's an official Homebrew formula. It will become an issue once we release 0.9.0 and Homebrew updates to that.

Steps to Reproduce

I recommend looking at CI output of job 238 from the PR for 0.8.14.

For reference, older PR with failed runs (though they're no longer relevan):

• 0.8.10 - especially this one has some earlier discussion about the issues.
• 0.8.12
• 0.8.13

ethereum/homebrew-ethereum#313, our most recent attempt, has fixed most issues, but the 0.4 series build still fails (see https://app.circleci.com/pipelines/github/ethereum/homebrew-ethereum/225/workflows/4358a1b1-2d43-4f32-92b7-be474226bbcb/jobs/242).

I'm pretty sure this will end up requiring a non-trivial source patch to build properly. That would be easiest to determine by someone with an actual osx system at hand.

I could pair up with @r0qs to give this a go, since I've got an OSX machine at home. We could use this as an investigation of sorts to see if it's even worthwhile investing time into this.

If you want to try, sure. Never hurts to try and if you actually manage to fix it, that's one less problem we have to think about. Just don't spend too much time on it because it's pretty low priority. These formulas have been broken for a while now and no one really complained. Probably no one builds older compilers from source on mac and for the latest one the official formula in Homebrew works.
