Check the DYNAMIC bit for input shared objects
Since the BFD section count may not be cleared for shared objects during
linking, we should check the DYNAMIC bit for input shared objects.
bfd/
PR ld/21626
* elf-properties.c (_bfd_elf_link_setup_gnu_properties): Check
the DYNAMIC bit instead of bfd_count_sections.
ld/
PR ld/21626
* testsuite/ld-i386/i386.exp: Run ld/21626 tests.
* testsuite/ld-x86-64/x86-64.exp: Likewise.
