Building gnuradio on an arm is silly :) (OK, mayb eif you have an armv8
server, but these do not exists yet) I am building gnuradio on a quad
A15 (limping across the OOM's). At the same time I built the toolchain
form an imge, installed the toolchain, configured and compiled gnuradio
on my x86.

Once we solve the mystery of the hardcoded paths in the QA code and work
out installing on the target from a cross build, things will be really nice.

On the subject of the email, I am wondering if the QA failure is relates
to the use of the hard float ABI. I'm switching my OE builds to armthf
now so I can compare my results with Tom's.
