H A DMakefile6c3b56b1 Mon Oct 30 14:43:51 CDT 2017 Matthias Kaehlcke <mka@chromium.org> x86/boot: Disable Clang warnings about GNU extensions

The kernel makes use of several GCC extensions, disable Clang warnings
about that in the boot code, as we already do for the rest of the kernel.

This suppresses the following warning when building with clang:

./include/linux/cgroup-defs.h:391:16: warning: field 'cgrp' with variable sized type 'struct cgroup' not at the end of a struct or class is a GNU extension [-Wgnu-variable-sized-type-not-at-end]
struct cgroup cgrp;
