I came up with this (creating the subdirs from 'configure').
This works in and out of tree, and with --disable-dependency-tracking.

Jim,
What do you think?
I couldn't find a simple target in the makefile that would create the subdirectories before anything else, yet not force a rebuild of everything every time.
For comparison, in 'coreutils' there is
   $(AM_V_at)${MKDIR_P} src
repeated several times in src/local.mk.

Comments welcomed,
