libunwind: don't mess around with ARM atomic detection

Browse Source 
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.

(From OE-Core rev: f2efadab8b1ab1c50584a39908673e1a6717f753)
