Add NaCl (NativeClient) specific classes Target_mips_nacl and
Target_selector_mips_nacl. gold/ * mips.cc (Target_mips_nacl): New class. (Target_selector_mips_nacl): New class. (target_selector_mips32): Rename from target_selector_mips32be and use Target_selector_mips_nacl instead of Target_selector_mips. (target_selector_mips32el): Rename from target_selector_mips32 and use Target_selector_mips_nacl instead of Target_selector_mips. (target_selector_mips64): Rename from target_selector_mips64be and use Target_selector_mips_nacl instead of Target_selector_mips. (target_selector_mips64el): Rename from target_selector_mips64 and use Target_selector_mips_nacl instead of Target_selector_mips. (Target_mips::mips_info): Add const attribute.
