Add parallel build functionality in ELPA 2013.08.004

Automake does normally not understand the dependencies of Fortran 90
modules, thus a parallel build will almost certainly fail.

As in ELPA 2011.12.002, ELPA 2013.08.004  now includes scripts from
the fdep project (see git.schokokeks.org/fdep) which cirumvents this
problem.

Thanks to Lorenz Huedepohl, now a parallel build works.

+# ===========================================================================
+#
+# SYNOPSIS
+#
+#   AX_CHECK_GNU_MAKE()
+#
+# DESCRIPTION
+#
+#   This macro searches for a GNU version of make. If a match is found, the
+#   makefile variable `ifGNUmake' is set to the empty string, otherwise it
+#   is set to "#". This is useful for including a special features in a
+#   Makefile, which cannot be handled by other versions of make. The
+#   variable _cv_gnu_make_command is set to the command to invoke GNU make
+#   if it exists, the empty string otherwise.
+#
+#   Here is an example of its use:
+#
+#   Makefile.in might contain:
+#
+#     # A failsafe way of putting a dependency rule into a makefile
+#     $(DEPEND):
+#             $(CC) -MM $(srcdir)/*.c > $(DEPEND)
+#
+#     @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND)))
+#     @ifGNUmake@ include $(DEPEND)
+#     @ifGNUmake@ endif
+#
+#   Then configure.in would normally contain:
+#
+#     AX_CHECK_GNU_MAKE()
+#     AC_OUTPUT(Makefile)
+#
+#   Then perhaps to cause gnu make to override any other make, we could do
+#   something like this (note that GNU make always looks for GNUmakefile
+#   first):
+#
+#     if  ! test x$_cv_gnu_make_command = x ; then
+#             mv Makefile GNUmakefile
+#             echo .DEFAULT: > Makefile ;
+#             echo \  $_cv_gnu_make_command \$@ >> Makefile;
+#     fi
+#
+#   Then, if any (well almost any) other make is called, and GNU make also
+#   exists, then the other make wraps the GNU make.
