From a45c8a275e5e4120f4f657379ff7b805d37eac3c Mon Sep 17 00:00:00 2001
From: Laura Abbott <labbott@redhat.com>

Subject: [PATCH] arm64: vdso: Explicitly add build-id option
To: Masahiro Yamada <yamada.masahiro@socionext.com>
To: Will Deacon <will.deacon@arm.com>
Cc: linux-kernel@vger.kernel.org
Cc: linux-arm-kernel@lists.infradead.org
Commit 691efbedc60d ("arm64: vdso: use $(LD) instead of $(CC) to
link VDSO") switched to using LD explicitly. The --build-id option
needs to be passed explicitly, similar to x86. Add this option.
Fixes: 691efbedc60d ("arm64: vdso: use $(LD) instead of $(CC) to link VDSO")
