Thus within a day an issue has been noted that we were unaware of and is being worked through a process to correct it, as would be the case with any deficiency on x86. The stack protection stuff will be fixed. Let's bike shed over the next nitpick nuance that the anti-ARM crowd want to throw in the way ;)

Am I missing something about using libssp?  It is literally a library,

gcc package removes libssp* unconditionally, so it isn't provided from
that and I can't find a stand-alone libssp package.
