vxworks.h (VXWORKS_LIBS_RTP): Alternative definition for 64bit configurations.

2017-06-27  Jerome Lambourg  <lambourg@adacore.com>

	* config/vxworks.h (VXWORKS_LIBS_RTP): Alternative definition for
  	64bit configurations.
  	(PTR_DIFF_TYPE): Alternative definition for TARGET_LP64.
  	(SIZE_TYPE): Likewise.
  	* config/vxworks.c (vxworks_emutls_var_fields): Use
  	long_unsigned_type_node instead of unsigned_type_node as the offset
	field type, which is "pointer" mode in emutls.c.
