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;
