I'd noticed that the cortexa8 toolchain was not available when I was starting 
to set up a new test build-environment with the latest versions.  We're using 
the TI AM3352.

Thanks,

I recommend using v7a. It uses the same settings as most armhf distributions, 
so this has better test coverage. I actually dropped the
cortexa8 toolchain from the latest OSELAS.Toolchain release.
It may be a bit slower depending on your hardware. What's your cpu anyways?
