Hi, Tom,
I tried these steps:
- Uninstalled gnuradio (make uninstall).
- apt-get update + apt-get upgrade for my ARM7 target (Ubuntu 13.04),
  which updated quite a bit of stuff.
- Deleted my gnuradio tree and re-cloned it.
- Checkout maint branch.
- Built as I have been doing.
- Same problem :(

Hi, Philip,
> Building gnuradio on an arm is silly :)
I bow to the sheer power of your A15 toolchain-rebuild cross-compile x86 
prowess. :)

For me, whenever I have tried to specify hard or soft float ABI, cmake fails. 
If I don't specify it, it just works...

Thanks!
