Subject: [PATCH] tests/tcg: gate pauth-% tests on having compiler support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Otherwise we end up failing to build our tests on CI which may have
older compilers that the user expects. We can get rid of this once we
can fallback to multiarch containers.
