The one step we left out of this over on -alpha, which is probably why
it didn't work for you the first time, is that you need to update
/usr/share/mk.  The idea is that the libc and awk need to be compiled
with -mieee so that floating point isn't broken.  This addition to
the CFLAGs has been made recently.
