From 29ea94e17c61b485f5cd1036e0ba8282b44ebb0e Mon Sep 17 00:00:00 2001 From: Brad King Date: Thu, 3 Mar 2022 12:52:37 -0500 Subject: BinUtils: Avoid llvm-ar on Apple platforms Since commit cf82300a63 (BinUtils: Clarify search logic and make it more consistent, 2021-05-27, v3.21.0-rc1~119^2~2) we correctly prefer the more-specific name `llvm-ar` over `ar` when using Clang. However, on Apple platforms, `llvm-ar` does not generate a symbol table that the Apple linker accepts. Fall back to `ar` on Apple platforms.
