When generating TLS dynamic relocations the existing xtensa BFD code treats linking to a PIE exactly as linking to a shared object, resulting in generation of wrong relocations for TLS entries. Fix that and add tests. bfd/ * elf32-xtensa.c (elf_xtensa_check_relocs): Use bfd_link_dll instead of bfd_link_pic. Add elf_xtensa_dynamic_symbol_p test when generating GOT entries. (elf_xtensa_relocate_section): Use bfd_link_dll instead of bfd_link_pic. ld/ * testsuite/ld-xtensa/tlspie.dd: New file. * testsuite/ld-xtensa/tlspie.rd: New file. * testsuite/ld-xtensa/tlspie.sd: New file. * testsuite/ld-xtensa/tlspie.td: New file. * testsuite/ld-xtensa/xtensa-linux.exp (TLS PIE transitions): New test.
