Right understand that.

Do note that the statx syscall to glibc stat64 interworking is already usable for
both cases as it is in sysdeps/unix/sysv/linux/statx_cp.*

Is see that for ARM32, following files are built:

sysdeps/unix/sysv/linux/arm/xstat.c
sysdeps/unix/sysv/linux/arm/fxstat.c
sysdeps/unix/sysv/linux/arm/lxstat.c
sysdeps/unix/sysv/linux/arm/fxstatat.c

sysdeps/unix/sysv/linux/xstat64.c
sysdeps/unix/sysv/linux/fxstat64.c
sysdeps/unix/sysv/linux/lxstat64.c
sysdeps/unix/sysv/linux/fxstatat64.c

My patch will switch the last 4 for ARM as well.

The first 4 will need more work as sym aliasing like
	strong_alias (__xstat64, __xstat)

will be needed in those ARM files (which in turn use i386).

Anyhow, let me test my patch and then we can take it from there !

Thx,
