This reverts commit 90d0d20508a91e7ea1e609e8aa9f9d1a28bb563e.
After further consideration, we've decided to remove this workaround:
* It only has an effect if the user has added `gnubin` from Homebrew Coreutils to PATH which is an unsupported setup
* It was intended to be applied only to a few select 3.8 and 3.9 versions that officially support Apple Silicon and only fail with Homebrew Coreutils in PATH because they have `config.*` from a too old version of Autoconf that doesn't support the Arm64 arch -- but
* CPython devs [didn't actually fix the problem in 3.10, either, only in 3.11](https://github.com/pyenv/pyenv/pull/2157#issuecomment-968055387), so we'd need to apply it to all 3.10 releases, too
* users started pushing this workaround into other unrelated branches because they were using the above unsupported setup. See https://github.com/pyenv/pyenv/pull/2190#pullrequestreview-835221952 for discussion.
This is needed to find other Python deps (e.g. libintl) in Homebrew if it has
nonstandard prefix (e.g. in Apple M1)
* Re-allow to search Homebrew for zlib everywhere
Link to the active version like other Homebrew deps --
this won't break when another binary-compatible version is installed.
Use a discovery method that doesn't break when other versions are present alongside.
Ensuring that all dirs in LDFLAGS exist is only needed for Ruby due to its `configure` requirements.
If some LDFLAGS entries point to a nonexisting path to which the user doesn't have permission. this causes a build failure.
In certain cases, a user wants to know the cached filename to add the file themselves,
see https://github.com/pyenv/pyenv/issues/1743 .
Since we report both a filename and a URL anyway, there's no reason to report a wrong one.
This PR fixes (currently harmless) warning on macOS when homebrew is *not* installed.
