Subject: [PATCH] kbuild, link-vmlinux: Don't delete output files with make -i
Date: Sun, 25 Apr 2021 14:35:21 -0700	[thread overview]
Message-ID: <20210425213521.3159899-1-ak@linux.intel.com> (raw)

From: Andi Kleen <andi@firstfloor.org>

make -i is useful to see output files which normally get deleted on an
error.  Make this work with link-vmlinux.sh too. Don't delete the output
files on error when make -i is used.
