[Bug 1820798] [NEW] hardening-check: add support for detecting stack clash protected binaries

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Ubuntu Foundations Team Bug Bot (crichton):

The security team is in the process of making -fstack-clash-protection
enabled by default in gcc-8/9 for 19.10 / 20.04. To support this it is
useful to be able to detect binaries which include this new feature via
hardening-check. Unlike previous features this can only be detected by
looking for the sequence of instructions which perform this feature in
the disassembly output via objdump.

** Affects: devscripts (Ubuntu)
