description:
Use rumphijack_dlsym() to figure out where __sysctl() is during
init.  Otherwise powerpc dlsym() DTWT and returns NULL.
(now i have no idea why dlsym() it works from rcinit(), but i'll
opt to not care)

Hah, only took 15min to debug that crap this time around.  I'm
quickly approaching zero-time with it.
