I am not aware of any such feature in 3.79 (that allows you to have any
knowlage of a.) what global target make was invoked with or b.) extract a
list of prerequisites for a given target at the global "scope" i.e. not
in the target scope).


Even though this is not really an answer to your question;
you may consider using an aproach similar to the following:

========= Makefile ========
PREREQS=a b c d

include test.mk

all: $(PREREQS)


======== test.mk ========
either:
-include $(patsubst %, %.mk, $(PREREQS))

or:

ifeq ($(findstring d, $(PREREQS)),d)
include d.mk
endif

==========================


Hope this helps,
