maint: more linking tweaks * configure.ac (--enable-link-all-dependencies): New option. (--enable-no-undefined): New option. Don't set NO_UNDEFINED_LDFLAG specially on Windows systems. * liboctave/link-deps.mk (LIBOCTAVE_LINK_DEPS): Include $(LAPACK_LIBS), $(BLAS_LIBS) and $(LIBS) in the list. * config-modules.awk: Add $(NO_UNDEFINED_LDFLAG) to LDFLAGS variables. * src/link-deps.mk (OCT_LINK_DEPS): Remove $(NO_UNDEFINED_LDFLAG from the list. * src/mkoctfile.cc.in, mkoctfile.in: Always link files with -loctinterp, -loctave, and -lcruft.
