Patches to make the tree cross-compilable

Howdy!

While procrastinating on this (US) holiday weekend, I've gotten together
some patches I've made to make the whole tree cross-compilable. I've put
them up on
ftp://ftp.netbsd.org/pub/NetBSD/misc/wrstuden/cross-compiling/cross-diffs.gz

There's a README which describes things more. I think they are complete,
but I might have snipped the don't-compile-tn3270 patch as it's a hack,
and tn3270 should be fixed. :-)

Please let me know what you think of (is wrong with :-) these patches.

Take care,

Bill
