pa.c (attr_length_call): Revise condition for long pc-relative branch. 

* pa.c (attr_length_call): Revise condition for long pc-relative branch.
	(output_call): Use "LONG_PIC_SDIFF" instruction sequence for long local
	calls on the SOM target.  Don't use "LONG_PIC_PCREL" call sequence on
	SOM target.
