[PATCH v2 2/2] gitlab-ci.yml: Add jobs to test CFI flags

[Daniele Buono <dbuono@linux.vnet.ibm.com>]

QEMU has had options to enable control-flow integrity features
for a few months now. Add two sets of build/check/acceptance
jobs to ensure the binary produced is working fine.

The two sets allow testing of x86_64 binaries for every target
that is not deprecated.

+# Since slirp callbacks are used in QEMU Timers, slirp needs to be compiled together
+# with QEMU and linked as a static library to avoid false positives in CFI checks.
+# This can be accomplished by using -enable-slirp=git, which avoids the use of
+# a system-wide version of the library

+# Split in two sets of build/check/acceptance because a single build job for every
+# target creates an artifact archive too big to be uploaded
