wasn't cortexa5 added already in:

    tune-cortexa5.inc: Add tune file for cortex-a5

I think that one was better, because it had optional neon support and
default DEFAULTTUNE should be something more generic (at least to stay
consistent with other tunes) it's DISTRO decision to select common
denominator (or more specific tunes for each MACHINE) for binary feeds
they want to manage.

    tune-*: define more generic DEFAULTTUNE to share feed between
machines
