I think it has become easier to override now and we just need to
update sysdeps/unix/sysv/linux/generic/bits/typesizes.h to set

#define __INO64_T_TYPE          __UQUAD_TYPE
#define __OFF64_T_TYPE          __UQUAD_TYPE
#define __OFF_T_MATCHES_OFF64_T        1
#define __INO_T_MATCHES_INO64_T        1

for new architectures (obviously not the ones that already use the
32-bit types). I haven't tries this, so there may be other things
that are required.

I think more than that would be needed to get struct stat to match and get 
things aliased for that (which is presumably desirable).

Looking at sysdeps/unix/sysv/linux/generic/bits/stat.h, there is at
least blkcnt_t that differs between stat and stat64.  And you probably
want to alias statfs and statfs64 as well, ie. fs{blk,fil}cnt_t.

Makes sense. Indeed that is a bit more work than I hoped, in particular
if we have to audit the uses of __WORDSIZE as well.
