Bug#738575: -momit-lock-prefix

[Marc Herbert <marc.herbert@gmail.com>]

Aurélien you are correct - some logic is required to use the
-momit-lock-prefix flag for Quark and not for all other CPUs. This is
possible in embedded, cross-compilation environments which build
everything from source (e.g. Yocto) but more difficult elsewhere.
