* rs6000.c (SMALL_DATA_REG): Register to use for small data relocs.
(print_operand): Use SMALL_DATA_REG for the register involved in
small data relocations.
(print_operand_address): Ditto.
* rs6000/linux.h (LINK_SPEC): Pass -dynamic-linker /lib/ld.so.1 if
-dynamic linker is not used.
* rs6000.md (call insns): For local calls, use @local suffix under
System V. Don't use @plt under Solaris.
