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* elf64-alpha.c (elf64_alpha_section_from_shdr): Delete outdated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.
