* arm.cc (Arm_scan_relocatable_relocs): New class.
	(Target_arm::relocate_special_relocatable): New method.
	(Arm_relocate_functions::arm_branch_common): Handle relocatable link.
	(Arm_relocate_functions::thumb_branch_common): Same.
	(Target_arm::scan_relocatable_relocs): Use Arm_scan_relocatable_relocs
	instead of Default_scan_relocatable_relocs.
	* target-reloc.h (relocate_for_relocatable): Let target handle
	relocation strategy Relocatable_relocs::RELOC_SPECIAL.
	* target.h (Sized_target::relocate_special_relocatable): New method.

// Perform target-specific processing in a relocatable link. This is
// only used if we use the relocation strategy RELOC_SPECIAL.
// RELINFO points to a Relocation_info structure. SH_TYPE is the relocation
// section type. PRELOC_IN points to the original relocation. RELNUM is
// the index number of the relocation in the relocation section.
// OUTPUT_SECTION is the output section to which the relocation is applied.
// OFFSET_IN_OUTPUT_SECTION is the offset of the relocation input section
// within the output section. VIEW points to the output view of the
// output section. VIEW_ADDRESS is output address of the view. VIEW_SIZE
// is the size of the output view and PRELOC_OUT points to the new
// relocation in the output object.
//
// A target only needs to override this if the generic code in
// target-reloc.h cannot handle some relocation types.
