+        * arm.cc (Target_arm::Target_arm): Move method definition outside of

+        (Target_arm::get_reloc_reloc_type): Change method to be non-static
+        and const.

+        member declaration.

+        Target_arm::Relocate::relocate,
+        Target_arm::Relocatable_size_for_reloc::get_size_for_reloc): Adjust
+        call to Target_arm::get_real_reloc_type.
+        (Target_arm::get_real_reloc_type): Use command line options to
+        determine real types of R_ARM_TARGET1 and R_ARM_TARGET2.
