sparc: Check bfd_link_executable for TLS check
Copied from x86, check bfd_link_executable, instead of bfd_link_pic, for TLS transition check. Not sure if it works correctly. All usages of bfd_link_pic should be audited. PR ld/22263 * elfxx-sparc.c (sparc_elf_tls_transition): Replace bfd_link_pic with !bfd_link_executable, !bfd_link_pic with bfd_link_executable for TLS check. (_bfd_sparc_elf_check_relocs): Likewise. (allocate_dynrelocs): Likewise. (_bfd_sparc_elf_relocate_section): Likewise.
