[PATCH 4/5] kbuild: disable -Winitializer-overrides for clang

[Ahmad Fatoum]

From: Ahmad Fatoum <a.fatoum at barebox.org>

clang warns about the intentional [0 ... N] = default followed by
per-entry overrides, e.g. in arch/arm/cpu/interrupts_64.c:

  arch/arm/cpu/interrupts_64.c:28:26: error: initializer overrides prior initialization of this subobject [-Werror,-Winitializer-overrides]

Disable it for clang, as Linux does.
