do we want the '-a'? The other arm (7) are of the format armv7a (no '-').
works for me either way.
While we are at it. How would we want ‘armv8.1-a’, ‘armv8.2-a’, ‘armv8.3-a'
formated as?
My preference is to drop the '-'. As for the '.', I'm not sure.. not something
we've run across before.
We could just drop it (the '.'), but it really depends on if armv81a would
confuse someone (familiar with arm) or not.
I would suggest to also sync with other distros and ensure that we dont
do something different. Its very costly later. Since applications get
ported to most common combination
Sync what part? naming of file? ( sorry lost regarding your comment)
