Subject: [PATCH 3/8] ARM: 8767/1: add support for building ARM kernel with clang

From: Stefan Agner <[email-masked]>
Date: Tue, 8 May 2018 22:50:38 +0100

(commit c1c386681bd73c4fc28eb5cc91cf8b7be9b409ba upstream)

Use cc-options call for compiler options which are not available
in clang. With this patch an ARMv7 multi platform kernel can be
successfully build using clang (tested with version 5.0.1).
