Subject: xntp3-5.88 ./configure -msupersparc

Configure should have an option to use -msupersparc on gcc
otherwise gcc does not use many important instructions available
on supersparc (including Sparc 10, Sparc 20 workstations).

I noticed that rerunning ./configure with a different option
didn't change the value (no I haven't read the documentation...)
but editing config.cache fixed it.

I build ntp3-5.88 with the patch I sent in earlier, it compiles
and I will be using it.

make clean does not remove the configure cache.

I repeated the build with -msupersparc:

zcat xntp3-5.88.tar.gz | tar xvf -
cd xntp3-5.88
mv xntpd/ntp_util.c xntpd/ntp_util.c.orig
cp ~/ntp/ntp_util.c xntpd/ntp_util.c
setenv CFLAGS "-O2 -g -msupersparc"
./configure --enable-hourly-todr-sync --enable-slew-always
unsetenv CFLAGS
make

and I installed and am running this version.
