ELF SEC_SMALL_DATA
For those ELF targets that have .sdata or .sbss sections, or similar sections, arrange to mark the sections with the SEC_SMALL_DATA flag. This fixes regressions in nm symbol type caused by removing .sdata and .sbss from coff_section_type with commit 49d9fd42ac. * elf32-m32r.c (m32r_elf_section_flags): New function. (elf_backend_section_flags): Define. * elf32-nds32.c (nds32_elf_section_flags): New function. (elf_backend_section_flags): Define. * elf32-ppc.c (ppc_elf_section_from_shdr): Set SEC_SMALL_DATA for .sbss and .sdata sections. * elf32-v850.c (v850_elf_section_from_shdr): Set SEC_SMALL_DATA for SHF_V850_GPREL sections. * elf64-alpha.c (elf64_alpha_section_from_shdr): Delete outdated FIXME. * elf64-hppa.c (elf64_hppa_section_from_shdr): Set SEC_SMALL_DATA for SHF_PARISC_SHORT sections. * elf64-ppc.c (ppc64_elf_section_flags): New function. (elf_backend_section_flags): Define. * elfxx-mips.c (_bfd_mips_elf_section_from_shdr): Set SEC_SMALL_DATA for SHF_MIPS_GPREL sections. Delete FIXME.
