Fix PR ld/22727 (TLS breakage in PIC/PIE mode on SPARC). There are actually 2 different bugs: 1. TLS transition is broken in PIE mode. 2. TLS is broken in PIC/PIE mode when the __tls_get_addr symbol is versioned (as is the case on Linux and Solaris at least). The 1st bug is fixed by reverting the problematic change for now (note that the associated test doesn't pass on SPARC because of another issue so there is no formal regression in the testsuite). The 2nd bug is fixed by changing the call to _bfd_generic_link_add_one_symbol on __tls_get_addr into a mere lookup in _bfd_sparc_elf_check_relocs. bfd/ * elfxx-sparc.c (_bfd_sparc_elf_check_relocs) <R_SPARC_TLS_GD_CALL>: Do a mere lookup of the __tls_get_addr symbol instead of adding it.

Fix PR ld/22263 on SPARC. This is -fpie -pie generating dynamic relocations in the text section, simply because no TLS transitions are applied in PIE mode. The meat of the patch is to turn calls to bfd_link_pic (info) in TLS-related code into !bfd_link_executable (info) and there are quite a lot of them... bfd/ * elfxx-sparc.c (sparc_elf_tls_transition): Turn call to bfd_link_pic into call to !bfd_link_executable and tidy up.
