I reported the problem with the athlon-xp.  My /etc/make.conf looks like
the following (when I wish to kill the loader and experience instant
reboots, that is ;-):

CPUTYPE?= athlon-xp
CFLAGS= -O -pipe
COPTFLAGS= -O -pipe

Note that I only see the problem when building the loader as part of a
buildworld.  Compiling just the boot stuff in /usr/src/sys/boot/ (i.e.,
without a bootstrapped gcc) results in a loader that works fine.  Thus, I
think defining CPUTYPE results in a gcc that produces a bad loader.
