Current Trusty based environment fail to complile with:
cc: error: unrecognized command line option ‘-fstack-protector-strong’
cc: error: unrecognized command line option ‘-fstack-clash-protection’
Upgrading to Xenial fix the first issue. I guess we need to check
availability of the second flag, or switch to build inside a container.
