 Google search says:
 
 "__builtin_return_address() doesn't supports other arguments than 0 in ARM"
 
http://stackoverflow.com/questions/9229702/gcc-return-address-of-calling-function-in-arm-architecture
 
 so it looks the only possible workaround is to make getreturnaddr()
 always return NULL on ARM (and MIPS etc)?
