Support for Ada on aarch64 with -mabi=ilp32
PR ada/80117
* system-linux-aarch64-ilp32.ads: New file.
* gcc-interface/Makefile.in (LIBGNAT_TARGET_PAIRS_COMMON): Rename
from LIBGNAT_TARGET_PAIRS.
(LIBGNAT_TARGET_PAIRS_32, LIBGNAT_TARGET_PAIRS_64): Define.
(LIBGNAT_TARGET_PAIRS): Use LIBGNAT_TARGET_PAIRS_COMMON, and
LIBGNAT_TARGET_PAIRS_64 or LIBGNAT_TARGET_PAIRS_32 for -mabi=lp64
or -mabi=ilp32, resp.
