Check if your mk.conf is setting COPTS or DEFCOPTS, basically you need
to ensure if you do tweak those that you include -O2 without which
the kernel is sufficiently big to overwrite the bootloader
which results in various failures - similar to what you are getting
I believe.

FWIW in my mk.conf I have:

.if ${MACHINE_ARCH} == "sparc"
DEFCOPTS=-O2 -msupersparc
.endif
