4KB for dynamic linking.  38KB for static linking.  

How many utilities are to be converted?  4KB (or 38KB)
can add up quickly.

Default 'make buildworld' options with CPUTYPE?=core2.  So, -O2.
I also tested with CFLAGS+=-static in w(1) and ls(1)'s Makefile.
The numbers that I showed are from 'make buildworld'.  The only
difference is w(1) and ls(1) with/without the libxo change.  I
don't need to cook the numbers to fabricate some issue.  Choose
your favorite CFLAGS.  Use svn to get w(1) and ls(1) with/without
libxo.  It's not difficult.
