(libinterp/corefcn/mxarray.h): Use script to substitute values. Depend on libinterp/corefcn/mxarray.in.h instead of Makefile * libinterp/corefcn/toplev.cc (octave_config_info): Don't include ALL_CFLAGS, ALL_CXXFLAGS, ALL_FFLAGS, ALL_LDFLAGS, of LIBFLAGS in the list. * libinterp/module.mk ($(SRC_DEF_FILES)): Don't depend on Makefile.

Depend on build-aux/subst-config-vals.sh instead of Makefile. (scripts/.DOCSTRINGS): Don't depend on Makefile. Do depend on timestamp file to ensure destination directory exists. * src/module.mk (src/$(host_triplet)-mkoctfile.cc, src/$(host_triplet)-octave-config.cc): Depend on build-aux/subst-cross-config-vals.sh instead of Makefile.
