    [ARC] Update warning reporting.
    
    MWDT compiler doesn't use eflags and makes use of 0x0c section. For
    those, silence the gnu warning system.

            * elf32-arc.c (arc_elf_merge_private_bfd_data): Complain about
            efalgs only when in/out exists.
            (elf32_arc_section_from_shdr): Don't complain about 0x0c section
            type.  It is mwdt compiler specific.
