Attempting to cross-compile newest -CURRENT

[Sean Welch]

Well, I gave it a shot last night with mixed results.  First
I had trouble with the toolchain patch I had copied out of 
the lists a while back.  Turns out it had a few extra line
breaks (not surprising since I cut and pasted from a webpage)
but it also seemed to have an extra "endif" in the part applied
to freebsd.h; the build failed pretty quickly on that last.  I
glued the lines together and got rid of the endif (adjusted all
the line numbers in the patch to take it into account) and it
applied just fine but then the build broke on ps (???) telling
me:

/usr/src/bin/ps/print.c: In function `state':
/usr/src/bin/ps/print.c:250: warning: comparison is always false due to limited
range of data type
*** Error code 1

Not sure it wasn't me, I cleaned out /usr/obj, did a make clean
under /usr/src, cvsup'd again, reapplied the patch and started
off the build again this morning.  I suspect it will fail in the
same place as I didn't see any changes to print.c, but again it
could be just me.

I figured I'd double check my procedure with you.

I'm still using the following for a make command:

make -DNO_BIND -DNOINFO -DNOGAMES -DNOPROFILE -DNOCRYPT -DNOSECURE -DNOLIBC_R -DNO_IPFILTER -DNOFORTH -DNO_FORTH TARGET_ARCH=powerpc buildworld | & tee /tmp/powerpc.log

Are all of these options still needed?  (It sure would be nice
to have an ssh!)

The patch I used on /usr/src is as follows (please post a new
copy if this one has problems):
