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.
