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.
