From b6a77bbebb4573d1899cc72e964e9875aae64436 Mon Sep 17 00:00:00 2001
From: Alexey Neyman <stilor@att.net>
Date: Thu, 14 Feb 2019 20:12:34 -0800
Subject: [PATCH] Check `output_elf' for being NULL
... before passing it to unlink(). GCC8.2 detects that one of the
branches in do_final_link() does not initialize it from its original
value, NULL.
