re PR target/62038 (Out of range branch target in thunk) 

PR target/62038
	* config/pa/pa.c (pa_output_function_epilogue): Don't set
	last_address when the current function is a thunk.
	(pa_asm_output_mi_thunk): When we don't have named sections or they
	are not being used, check that thunk can reach the stub table with a
	short branch.
