Bug #20499: Ruby builds on macOS store absolute paths for AR and NM in rbconfig since Ruby 3.2.3/3.3.0

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 3.2.4 (2024-04-23 revision af471c0e01) [arm64-darwin23]
• Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN

[Bo98 (Bo Anderson)]

This is a regression introduced by https://github.com/ruby/ruby/commit/038f9ade3c4d965415e4956561975454cf9eeb21 and causes various downstream problems such as https://github.com/ruby/prism/issues/2716. Development tools on macOS are relocatable - Xcode.app can exist anywhere on the system so it cannot be assumed that the location on the build machine matches the location on the running machine. If an absolute path must be used, /usr/bin/nm and /usr/bin/ar are acceptable.

[Bug #20499] Use consistent version tools with CC

As Apple Xcode is relocatable and selectable with xcode-select, use
consistent versions of commands in the same location.
