invoke.texi (powerpc msdata-data): Static data doesn't go in small data sections.

	* doc/invoke.texi (powerpc msdata-data): Static data doesn't go in
	small data sections.
	* config/rs6000/rs6000.c (rs6000_elf_in_small_data_p): Make global.
	* config/rs6000/rs6000-protos.h: (rs6000_elf_in_small_data_p): Declare.
	* config/rs6000/sysv4.h (ASM_OUTPUT_ALIGNED_LOCAL): Rename to..
	(ASM_OUTPUT_ALIGNED_DECL_LOCAL): ..this, adding extra parm.  Don't
	output locals to sbss if !rs6000_elf_in_small_data_p.
	(ASM_OUTPUT_ALIGNED_BSS): Adjust for above.
