libobjc, Darwin : Fix powerpc encoding regression. 

This corrects a typo in the recipe for the special type alignment
rules that are used for 32bit powerpc Darwin platforms.

libobjc/ChangeLog:

	* encoding.c (_darwin_rs6000_special_round_type_align):
	Use DFMode in the emulation of the special round type.

(cherry picked from commit dcd9800fcd)
