You could do something like this:

1. Rename your current Makefile to include-me.mak
2. The new top-level Makefile looks like this:

    BUILD := foo
    include include-me.mak
    BUILD := bar
    include include-me.mak
    BUILD := baz
    include include-me.mak

or if you want to get really fancy you could do

    define INCLUDE_IT
        BUILD := $1
        include include-me.mak
    endef
    BUILDS := foo bar baz
    $(foreach B,$(BUILDS),$(call INCLUDE_IT,$B))

You will have problems with globally defined variables like CFLAGS which 
are not $(BUILD) specific, so you'll have to fix that in include-me.mak.
