	callback if avr_arch->flash_pm_offset = 0.
	(avr_asm_named_section) <avr_need_copy_data_p>: Skip setting it
	for rodata if avr_arch->flash_pm_offset != 0.
	(avr_encode_section_info) [AVR_TINY]: Adjust comment.
	* config/avr/genmultilib.awk (dir_rcall, opt_rcall): New vars.
	(opts) [AVR_ISA_RCALL]: Append opt_rcall.
	(m_options): Append opt_rcall.
	(m_dirnames): Append dir_rcall.
	* config/avr/t-multilib: Regenerate.
	* configure.ac [target=avr]: Check whether avrxmega3 default
	linker description file works as needed.
