elf_cris_link_hash_table_create, elf_cris_adjust_dynamic_symbol,
elf_cris_size_dynamic_sections, elf_cris_finish_dynamic_symbol,

functions.
(cris_elf_howto_table) <R_CRIS_8_PCREL, R_CRIS_16_PCREL,
R_CRIS_32_PCREL>: Correct comments. Set pcrel_offset to false.

R_CRIS_32_GOTREL, R_CRIS_32_PLT_GOTREL, R_CRIS_32_PLT_PCREL>:
New HOWTO members for new relocs.
(cris_reloc_map): Map new relocs.
(ELF_DYNAMIC_INTERPRETER): Define.
(PLT_ENTRY_SIZE): Define.
(elf_cris_plt0_entry, elf_cris_plt_entry, elf_cris_pic_plt0_entry,
elf_cris_pic_plt_entry): New, PLT templates.
(struct elf_cris_pcrel_relocs_copied, struct
elf_cris_link_hash_entry, struct elf_cris_link_hash_table): New.
(elf_cris_link_hash_traverse, elf_cris_hash_table): Define.
(cris_final_link_relocate): Check that 16-bit GOT relocs have
positive values. Adjust PCREL relocs to be relative to location
after relocation.
(cris_elf_relocate_section): Handle relocations to dynamic
objects. Handle new relocations. Call error handler when seeing
non-PIC relocation for read-only sections while generating shared
object.
(cris_elf_check_relocs): Set reference counts for GOT and PLT
entries.
