Subject: [PATCH] kbuild, link-vmlinux: Don't delete output files with make -i

From: Andi Kleen <andi@...stfloor.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.
