* elf32-sh.c (elf_sh_plt0_entry_be, elf_sh_plt0_entry_le): Copy

	contents of .got.plt[2] to tr0, not address of .got.plt.
	(sh_elf_finish_dynamic_symbol): Do not apply GOT_BIAS when
	patching absolute plt entry. For shmedia plt entry, set bottom bit
	of branch to plt0 as this is a branch to an shmedia instruction.
	* elf64-sh64.c (elf_sh64_plt0_entry_be, elf_sh64_plt0_entry_le):
	Copy contents of .got.plt[2] to tr0, not address of .got.plt.
	(elf_sh64_plt_entry_be, elf_sh64_plt_entry_le): Use ptrel to
	branch to plt0.
	(sh64_elf64_finish_dynamic_symbol): Do not apply GOT_BIAS when
	patching absolute plt entry. For shmedia plt entry, branch to
	plt0 is now ptrel, so use relative offset.  Set bottom bit of
	branch target as it is a branch to an shmedia instruction.
