From: Nick Desaulniers <ndesaulniers@xxxxxxxxxx> Subject: Partially revert "ARM: 8905/1: Emit __gnu_mcount_nc when using Clang 10.0.0 or newer" This partially reverts commit b0fe66cf095016e0b238374c10ae366e1f087d11. The minimum supported version of clang is now clang 10.0.1. We still want to pass -meabi=gnu.
