It's a lot more than a dozen symbols for anything other than a trivial
`hello world' program.

If you really want to take advantage of the "static binary speed increases"
you really want to crunchgen all of /bin, /sbin, /usr/bin, /usr/sbin, and
some of /usr/libexec into one huge binary so everything is always memory
resident (plus you get the disk and memory saving of dynamic linking too).
When ya gonna add a "MKCRUNCHGEN=yes" flag 8^)
