Graceful degrade if Binutils PR21472 is not available.
PR target/81072
* configure.ac [target=avr]: WARN instead of ERROR if avrxmega3
.rodata in flash test fails.
(HAVE_LD_AVR_AVRXMEGA3_RODATA_IN_FLASH): Define it if test passes.
* confgure: Regenerate.
* config.in: Regenerate.
* config/avr/avr.c (avr_asm_named_section)
[HAVE_LD_AVR_AVRXMEGA3_RODATA_IN_FLASH]: Only trigger
__do_copy_data for stuff in .rodata if flash_pm_offset = 0.
(avr_asm_init_sections): Same.
