BFD: Use `bfd_is_abs_symbol' to determine whether a symbol is absolute
Use `bfd_is_abs_symbol' to determine whether a symbol is absolute,
avoiding a problem with ordinary symbols defined in a linker script
outside an output section definition. Such symbols have its owning
section set to the absolute section up to the final link phase. A flag
has been added to the link hash to identify such symbols. Rather than
checking the flag by hand, use the macro that does it uniformly for all
users.

* elf32-nds32.c (nds32_elf_relax_loadstore): Use
`bfd_is_abs_symbol' rather than `bfd_is_abs_section' in checking
whether the symbol is absolute.
(nds32_elf_relax_lo12): Likewise.
* elfnn-aarch64.c (elfNN_aarch64_final_link_relocate): Likewise.
(elfNN_aarch64_check_relocs): Likewise.
* xcofflink.c (xcoff_need_ldrel_p): Likewise.
(bfd_xcoff_import_symbol): Likewise.
(xcoff_write_global_symbol): Likewise.
