    [PR ld/22263][PR ld/25056] arm: Avoid dynamic TLS relocs in PIE

    Dynamic relocs are only needed in an executable for TLS symbols if
    those are defined in an external module and even then TLS access
    can be relaxed to use IE model instead of GD.

    Several bfd_link_pic checks are turned into bfd_link_dll checks
    to fix TLS handling in PIE, for the same fix some other targets
    used !bfd_link_executable checks, but that includes relocatable
    objects so dll seems safer (in most cases either should work, since
    dynamic relocations are not applied in relocatable objects).

    On arm* fixes

        * elf32-arm.c (elf32_arm_tls_transition): Use bfd_link_dll instead of
        bfd_link_pic for TLS checks.
        (elf32_arm_final_link_relocate): Likewise.
        (allocate_dynrelocs_for_symbol): Likewise.
