+	(PLT_ENTRY_SIZE): Return the appropriate *_PLT_ENTRY_SIZE.
+	(elf32_arm_plt0_entry): Rename PLT_ENTRY_SIZE to
+	ARM_PLT_ENTRY_SIZE.
+	(elf32_arm_plt_entry): Likewise.
+	(elf_backend_plt_header_size): Likewise.
+	(elf32_thumb_plt0_entry): New global.
+	(elf32_arm_finish_dynamic_sections): Use it.  Put Thumb entries
+	into .plt.thumb.
+	(elf32_thumb_plt_entry): New global.
+	(elf32_arm_finish_dynamic_symbol): Use it.  Use .thumb.plt for

+	Determine if relocation needs a PLT entry.  Set first_rel_type if
+	this is the first time we encounter the symbol
+	(elf32_arm_adjust_dynamic_symbol): Create PLT entries for Thumb
+	functions as well.
+	(elf32_arm_size_dynamic_sections): Handle .plt.thumb like .plt.
