lang/gcc5: add patch to avoid declaring a prototype of host_detect_local_cpu
on platforms which do not include driver-arm.o in gcc/config.host, and do
not have this function. such as netbsd/arm.

an alternative would be to add driver-arm.o for the netbsd/arm case too, but
it would be diverging from netbsd base gcc, and /proc/cpuinfo which is needed
for this function to do anything useful is empty at least on my machine.

(I still can't complete a build on ARM)

$NetBSD: patch-gcc_config_arm_arm.h,v 1.1 2016/09/30 04:06:07 maya Exp $

needs host_extra_gcc_objs="driver-arm.o" in gcc/config.host.
otherwise you get an error:
undefined reference to `host_detect_local_cpu(int, char const**)

the function relies on /proc/cpuinfo to exist and provide useful
information, and is used for -m{arch,tune,cpu}=native.
