[uclibc-ng-devel] [PATCH] xtensa: Add time64 support.

- xtensa is the second architecture that supports time64 inside uClibc-ng. - Linux Kernel always uses 32bit time variables inside `stat` structures, so there is a need to use `st_atime`, `st_mtime` and `st_ctime` structures with the same 32bit-wide `tv_sec` and `tv_nsec` variables even if time64 is enabled.
