    PR25191, internal error in _bfd_elf_set_section_contents

    This PR copies a fuzzed PE input file to ELF output, in the process
    confusing the ELF backend by copying COFF-only section flags to the
    output.  SEC_COFF_SHARED has the same value as SEC_ELF_COMPRESS.  One
    approach to fixing this problem is of course not to reuse flag bits,
    but we've run out.  So this patch only copies section flags that are
    in the bfd_applicable_section_flags set when changing the flavour of
    the output file.

        PR 25191
        * objcopy.c (is_nondebug_keep_contents_section): Use bfd_get_flavour.
        (copy_object): Likewise.
        (setup_section): Likewise.  If flavour of input and output files
        differ, restrict section flags to the intersection of input and
        output bfd_applicable_section_flags.
