[RS6000] Make -msingle-pic-base remove the ELFv2 global entry code

For other ABIs, -msingle-pic-base makes gcc omit loading of the PIC
register in function prologues.  This patch makes the option affect
ELFv2 too.

* config/rs6000/rs6000.c (rs6000_emit_prologue): Don't set
r2_setup_needed when TARGET_SINGLE_PIC_BASE.
(rs6000_output_mi_thunk): Likewise.
