PR27725, better objcopy -p times
Nanosecond rather than second resolution.
PR 27725
* configure.ac: Check for sys/time.h and utimensat. Use standard
checks for mkstemp and mkdtemp. Whitespace. Check for nanosecond
members of struct stat.
* rename.c: Prefer sys/time.h for utimes over utime.h for utime.
(STAT_TIMESPEC, STAT_TIMESPEC_NS): Define
(get_stat_atime_ns, get_stat_mtime_ns): New inline functions.
(get_stat_atime, get_stat_mtime): Likewise.
(set_times): Choose first available of utimensat, utimes, utime.
Use above inline functions to set timespec and timeval values.
* configure: Regenerate.
* config.in: Regenerate.
* testsuite/binutils-all/objcopy.exp (objcopy_test): Add test of
file timestamp when --preserve-dates is used.
