Spotted these while cleaning up <sys/cdefs.h> --- if we remove __USE_XOPEN2K8, libchrome decides you "must" have futimes. Adding the missing functions (all just alternative interfaces to utimensat(2) system call) lets us clean up without breaking anything. Change-Id: If44fab08ee3de0e31066d650d128a3c96323529b
