I knew why these functions are not. Some syscall functions
are not in Symbol.map. Please apply following patch.

I found above functions by runing following command:
$ cd /usr/obj/usr/src/lib/libc
$ readelf -sW *.o | fgrep -e GLOBAL -e WEAK | fgrep -v -e HIDDEN -e UND | fgrep FUNC | awk '{print $8}' | while read i; do echo -n "$i "; if fgrep -qw $i Version.map; then echo "*EXIST*"; else echo "*NONE*"; fi; done
