From ef8c4ed9db80261f397f0c0bf723684601ae3b52 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Mon, 17 Sep 2018 19:31:57 -0700 Subject: kbuild: allow to use GCC toolchain not in Clang search path When using a GCC cross toolchain which is not in a compiled in Clang search path, Clang reverts to the system assembler and linker. This leads to assembler or linker errors, depending on which tool is first used for a given architecture. It seems that Clang is not searching $PATH for a matching assembler or linker. Make sure that Clang picks up the correct assembler or linker by passing the cross compilers bin directory as search path. This allows to use Clang provided by distributions with GCC toolchains not in /usr/bin.
