If that's all the directories you have in build_arm_nofpu, then you
don't have a successful build. On my machine, using pretty much the
default configuration options, I see (the machine I checked was
running r1295):

ls ~/gumstix/gumstix-buildroot/build_arm_nofpu/

bplay installs a signal handler to catch SIGINT (Control-C). I think
that killall sends a SIGTERM and brec/bplay doesn't seem to install a
handler for that.

You might want to try using:

killall -INT brec
