make clean-src
make clean-srcdir

or MKOBJDIRS=no make clean

?

By creating them automatically.
Using .error might be a bit harsh.

Sure.  It is inlcuded in my mk files collection:

http://www.crufty.net/ftp/pub/sjg/mk.tar.gz

which is a symlink to the latest version:

http://www.crufty.net/ftp/pub/sjg/mk-20110808.tar.gz

and

ftp://ftp.netbsd.org/pub/NetBSD/misc/sjg/mk-20110808.tar.gz

We've been using it in the Junos build since 2004

BTW the above archive also contains the bits needed to leverage 
meta mode in recent make - as described at BSDcan.

We are about to finish our roll-out of this, and I'll be 
updating mk.tar.gz with the latest editions of dirdeps.mk etc.
