Root partition and usrland on one slice, /usr/local ports and src on another

[lankfordandrew at charter.net]

It's been quite a while since I've tried a rebuild, but I think the
problems appeared early when gcc and gas and dependencies were being
built. I tried just symlinks, then different settings of the build
variables, and (IIRC) enabling clang. Perhaps I could start fresh with
11.1, but then perhaps placing everything on one slice is the most
straightforward solution.

 I do that for years for eight major releases at least and have no
problems
 making symlinks /usr/src -> /usr/local/src, /usr/obj ->
/usr/local/obj,
 /usr/ports -> /usr/local/ports.

 What kind of problems do you have while building world and
 why do you think that problems are due to symlinks?
