eliminate recursive make invocations in doc directory tree * doc/module.mk: New file created from doc/Makefile.am, doc/doxyhtml/Makefile.am, doc/liboctave/Makefile, doc/interpreter/Makefile.am, and doc/refcard/Makefile. * configure.ac (AC_OUTPUT): Don't generate doc/Makefile, doc/doxyhtml/Makefile, or doc/interpreter/Makefile. * Makefile.am (.NOTPARALLEL, AUTHORS, BUGS, INSTALL.OCTAVE): Delete targets. * config-images.sh, find-docstring-files.sh, geometryimages.m, graphics_properties.mk, images.awk, interpimages.m, plotimages.m, sparseimages.m, splineimages.m: Adapt to Makefile changes. * octave.texi, liboctave.texi: Use unique version file names. * etc/module.mk: Ensure icons build directory is created. (etc/icons/octave-logo.ico): Fix file name. * examples/module.mk (examples_code_SRC): New variable. * doc/Makefile.am, doc/doxyhtml/Makefile.am, doc/liboctave/Makefile.am, doc/interpreter/Makefile.am, doc/refcard/Makefile: Delete.

-# Subdirectories in which to run `make all'.  Including "." before
