From 31043704558efdeb25e2be9b03f211513047c635 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 14 Nov 2020 12:37:39 +0100 Subject: [PATCH] build: detect broken make version on macOS Apple ships a broken make version with the Xcode command line tools. Homebrew installs make as gmake by default in order to not collide with Apple's version.
