Subject: [RFC Patch v1 51/55] modpost: Ignore ARC specific non-alloc section

From: Vineet Gupta <vgupta@...opsys.com>

ARC relocatable object files contain one/more .gnu.linkonce.arcextmap.*
sections (collated into .arcextmap in final link). These sections are
used by debuggers to display the extension instructions and need-not be
loaded by target (hence !SHF_ALLOC)

This patch adds the section to modpost's ignore list to avoid the
following

======================>8========================
WARNING: vmlinux.o (.gnu.linkonce.arcextmap.inst.3.5.8): unexpected
non-allocatable section.
Did you forget to use "ax"/"aw" in a .S file?
Note that for example <linux/init.h> contains
section definitions for use in .S files.
======================>8========================
