Subject: [PATCH 3.12 177/181] builddeb: use $OBJCOPY variable instead of objcopy

From: Fathi Boudra <fathi.boudra@...aro.org>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 6b4a144a92ab81a1f45fb9b12aebaaaee0d08120 upstream.

In cross-build environment, we expect to use the cross-compiler objcopy
instead of the host objcopy.

It fixes following build failures:
objcopy --only-keep-debug lib/modules/3.14/kernel/net/ipv6/xfrm6_mode_tunnel.ko /srv/build/linux/debian/dbgtmp/usr/lib/debug/lib/modules/3.14/kernel/net/ipv6/xfrm6_mode_tunnel.ko
objcopy: Unable to recognise the format of the input file `lib/modules/3.14/kernel/net/ipv6/xfrm6_mode_tunnel.ko'
