A new struct __stat{64}_t64 type is added with the required __timespec64 time definition. Only LFS is added, 64-bit time with 32-bit offsets is not supposed to be supported (no existing glibc configuration supports such a combination). It is done with an extra __NR_statx call plus a conversion to the new __stat{64}_t64 type. The statx call is done only for 32-bit time_t ABIs. Internally some extra routines to copy from/to struct stat{64} to struct __stat{64} used on multiple implementations (stat, fstat, lstat, and fstatat) are added on a extra implementation (stat_t64_cp.c). Alse some extra routines to copy from statx to __stat{64} is added on statx_cp.c. Checked with a build for all affected ABIs. I also checked on x86_64, i686, powerpc, powerpc64le, sparcv9, sparc64, s390, and s390x. Reviewed-by: Lukasz Majewski <lukma@denx.de>
