Change the .section directive for the AVR assembler so that the .noinit section is always given the ELF NOBITS section type.
PR gas/23570
* config/tc-avr.c (md_pseudo_table): Add entry for "secction".
(avr_set_section): New function. Ensures that the .noinit section
gets the NOBITS ELF section type.
