dhcp suite build process improvement patch

[Gregory Steuck <greg_(_at_)_nest_(_dot_)_cx>]

Hello,

this is a gentle reminder that a patch improving dhcp suite build
process is awaiting your review in
http://cvs.openbsd.org/cgi-bin/wwwgnats.pl/full/2715

Even though 50 to 25 seconds on a venerable i386 is almost nothing
it may be more impressive on some older systems.

Thanks
Greg
