Partial ILP32 support for aarch64.
* sysdeps/aarch64/crti.S: Add include of sysdep.h.
(call_weak_fn): Use PTR_REG to get correct reg name in ILP32.
* sysdeps/aarch64/dl-irel.h: Add include of sysdep.h.
(elf_irela): Use AARCH64_R macro to get correct relocation in ILP32.
* sysdeps/aarch64/dl-machine.h: Add include of sysdep.h.
(elf_machine_load_address, RTLD_START, RTLD_START_1, RTLD_START,
elf_machine_type_class, ELF_MACHINE_JMP_SLOT, elf_machine_rela,
elf_machine_lazy_rel): Add ifdef's for ILP32 support.
* sysdeps/aarch64/dl-tlsdesc.S (_dl_tlsdesc_return,
_dl_tlsdesc_return_lazy, _dl_tlsdesc_dynamic,
_dl_tlsdesc_resolve_hold): Extend pointers in ILP32, use PTR_REG
to get correct reg name for ILP32.
