    PR24015, glibc-2.28 on little-endian mips32 broken

    Commit 2bf2bf23da exposed a bug on targets that create common sections
    other than the standard ELF SHN_COMMON.  If these are output by ld -r,
    then their type becomes SHT_PROGBITS unless the target handles them
    specially (eg. by elf_backend_special_sections), and if they are
    merged into .bss/.sbss by ld -r then that section becomes SHT_PROGBITS.

    Worse, if they are output by ld -r, then their size is increased by
    bfd_generic_define_common_symbol during final link, which leads to
    bogus file contents being copied to output.

    For mips, it seems to me that the .scommon section should not be
    output for ld -r, but I haven't made that change in this patch.

        PR 24015
        * elf.c (bfd_elf_get_default_section_type): Make common sections
        SHT_NOBITS.
        * linker.c (bfd_generic_define_common_symbol): Clear
        SEC_HAS_CONTENTS.
