Correct.  A number of symbols referred to by programs via the nlist
system call have recently been made static, and strip -x removes them.
This will also cause problems with vmstat and iostat, and others that
I forget.

I think this is more a documentation problem than a system problem: if
you make the kernel without -g, you don't run into this problem, and
if you do use -g, strip -d does what you want.
