libunwind: don't mess around with ARM atomic detection

This recipe explictly sets -DAO_USE_PTHREAD_DEFS on ARM, but with libunwind 1.2
this causes the linker to fail:

  hidden symbol `__sync_synchronize' in libgcc.a(linux-atomic.o) is referenced by DSO

Removing these defines lets configure do the right thing and build libunwind.
