This allows you to use 'buildkernel' to cross build a kernel and not use
/usr/src for your sources.  Thus, for example:

- Assume full current sources at /usr/src
- Assume local work tree of kernel sources at /usr/work/jhb/p4/proc

% cd /usr/src
% make TARGET_ARCH=alpha buildworld
% cd /usr/work/jhb/p4/proc/alpha/conf
% make LINT
% cd /usr/src
% make TARGET_ARCH=alpha NO_MODULES=yes KERNCONF=LINT
KERNSRCDIR=/usr/work/jhb/p4/proc buildkernel

cross builds an Alpha LINT kernel of my process locking branch.
I used this to cross build Alpha LINT and sparc64 and ia64 GENERIC
on the jhb_proc branch today.
