Sure, but its a known problem that if you have something in mk.conf
that causes -O2 to be dropped from the kernel compile you will
produce a kernel that is too big.

Try rm'ing init_main.o or something and re-run build.sh -m sparc etc
and confirm that -O2 was included in the compiler args.  If not
take a look at mk.conf.  FWIW I have (on the i386 I use to build sparc):

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

which works for -current but not 1.6 - but 1.6 doesn't support a simple
build a kernel arg to build.sh so I build those on the sparc box itself.
