$(word) or $(words) are in 3.79 but not 3.77. The MAKEFILE_LIST is new
in 3.80. It is used inside the nonrecursive Makefile fragment in the
subdirectory:

local_lib  := libnl.a
local_src  := $(wildcard $(subdirectory)/*.F)
path_srcs  += $(local_src)

local_src  := $(patsubst $(subdirectory)/%.F,%.F,$(local_src))
local_objs := $(subst .F,.o,$(local_src))

libraries += $(local_lib)
sources   += $(local_src)

$(local_lib): $(local_objs)
        $(AR) $(ARFLAGS) $@ $^
--------------------------------
We have to edit the name of local_lib here, so there is no real
hardship in editing a local_dir as well. Both versions are straight out
of the new O'Reilly book, except that we're using Fortran instead of C.
