I gave it some more thought, and I think we should actually stay
with sys_open_by_handle_at and sys_openat, but do it a little differently:

Forcing O_LARGEFILE is probably what we want for all architectures
going forward, so we should change asm-generic/unistd.h to use sys_openat
for compat mode, and override it for tile32 compat, which is the only
existing user of this table at the moment and which needs to
retain the existing behavior.
