rs6000: fix PTR_SIZE in rs6000.c

The recent change to rs6000.c for DWARF in AIX references the macro
PTR_SIZE that only is defined in dwarf2out.c.  This patch changes the
reference to the equivalent POINTER_SIZE_UNITS defined in defaults.h.

gcc/ChangeLog:

	* config/rs6000/rs6000.c (rs6000_option_override_internal):
	Change PTR_SIZE to POINTER_SIZE_UNITS.
