[LLD][ELF][AVR] Propagate ELF flags to the linked image The `e_flags` for a ELF file targeting the AVR ISA contains two fields at the time of writing: - A 7-bit integer field specifying the ISA revision being targeted - A 1-bit flag specifying whether the object files being linked are suited for applying the relaxations at link time The linked ELF file is blessed with the arch revision shared among all the files. The behaviour in case of mismatch is purposefully different than the one implemented in libbfd: LLD will raise a fatal error while libbfd silently picks a default value of `avr2`. The relaxation-ready flag is handled as done by libbfd, in order for it to appear in the linked object every source object must be tagged with it.
