[gcc-7-arm] Backport -moutline-atomics flag

[Pop, Sebastian]

Thanks Richard for your recommendations.
I am still discussing with Kyrill about a good name for the branch.
Once we agree on a name we will commit the patches to that branch.

    Given the branch doesn't exist yet can you eventually push this series to
    a user branch (or a amazon vendor branch)?

    You failed to CC arm folks so your mail might have been lost in the noise.

    Thanks,
    Richard.
