* elf32-sparc.c (_bfd_sparc_elf_howto_table): Remove support for
R_SPARC_UA64. (elf32_sparc_check_relocs): Likewise. Only create .rela section for alloced sections in shared libraries. (elf32_sparc_relocate_section): Likewise. Remove redundant check. Optimize unaligned reloc usage. * elf64-sparc.c (sparc64_elf_relocate_section): Remove redundant check. * testsuite/gas/sparc/unalign.s: Remove .uaxword test. * testsuite/gas/sparc/unalign.d: Adjust accordingly.
