I'd like to qualify the whole idea to put compilation data in some subdirectory
of /usr/src as harmful. `make buildkernel' places it in more reasoned
place (but /usr/obj/usr/src/sys/compile/i386/zzz is IMHO preferrable than
current /usr/obj/usr/src/sys/zzz). Building in /usr/src/sys/compile is
legacy issue which should be IMO removed, and /usr/sbin/config should require
explicit way in its command line.

But this is bound with another /usr/src pollutions. E.g. one cannot place
kernel config in /etc and say "config /etc/kernel.config/nn12" without
moving it and current directory to /usr/src/sys/i386/conf or placing
symlink in it. LINT is also made in /usr/src/sys/${arch}/conf, not /etc
or subdirectory of /etc.

make buildkernel is rather easy way to work it around: in any case object
tree is machine-dependent, and one yet another directory does not destroy
anything. ;|
