PR11290, avr-ld "out of range error" is confusing

Don't overload bfd_reloc_outofrange with what is really a domain error
(target at odd address), or an overflow.

	PR 11290
	* reloc.c (bfd_reloc_other): Correct comment.
	* elf32-avr.c (avr_final_link_relocate): Return bfd_reloc_other
	for unaligned reloc target values.  Return bfd_reloc_overflow
	when stubs are too far away and when R_AVR_LDS_STS_16,
	R_AVR_PORT6, or R_AVR_PORT5 overflow.
	(elf32_avr_relocate_section): Report more descriptive relocation
	errors.
	* bfd-in2.h: Regenerate.
