Ken,

have you read:
http://gnuradio.org/redmine/projects/gnuradio/wiki/TutorialsDebugging?

Run 'ctest -V -R fft_filter' to activate verbosity and limit the tests
by a regex.

The make system will do this for you. If you change a file, it will
compile only the minimum necessary set.

There currently open issues w/ ARM. I'm not sure this is one of them,
but VOLK code on ARM is curently heavily under research.

You can do that, but in general, starting with some print statements is
usually more helpful (use ctest -V). I'd wait until someone from the ARM
experts has had a look at this.
