Hi,

	Ports should call final_start_function and final_end_function to get 
proper debug info for the thunk as per 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55257#c3 . Fixes failing 
tests in g++.dg for arm-*-*eabi.

Tested on arm-linux-gnueabi cross for armv7-a, arm/thumb2 and armv5t on 
qemu. Applied.

Thanks,
Ramana

final_end_function.
