Borislav Petkov c583491719 x86: Deprecate a.out support ...

mainline inclusion
from mainline-v5.0
commit eac616557050737a8d6ef6fe0322d0980ff0ffde
category: bugfix
bugzilla: 13690
CVE: CVE-2019-11191

-------------------------------------------------

Linux supports ELF binaries for ~25 years now.  a.out coredumping has
bitrotten quite significantly and would need some fixing to get it into
shape again but considering how even the toolchains cannot create a.out
executables in its default configuration, let's deprecate a.out support
and remove it a couple of releases later, instead.
