From: Andrew Pinski <apin...@cavium.com>
This converts dl-tlsdesc.S code over to use the new macros which allows for
sharing between ILP32 and LP64 code.
* sysdeps/aarch64/dl-tlsdesc.S (_dl_tlsdesc_return): Use PTR_REG.
(_dl_tlsdesc_dynamic) : Use PTR_REG, PTR_SIZE.
(_dl_tlsdesc_resolve_hold) : Likewise.
(_dl_tlsdesc_resolve_rela) : Likewise.
(_dl_tlsdesc_return_lazy) : Likewise.
(_dl_tlsdesc_undefweak) : Likewise.
