I'm not sure I understand your requirements, but here is one way to
do it which I think meets them:
Change the entry for the link step, so it always
compiles the global array.:
foo: foo1.o foo2.o ... global_array.o
cc -o foo foo1.o foo2.o .. global_array.o -lfoo -lbar
to:
foo: foo1.o foo2.o ... global_array.c
cc -c global_array.c
cc -o foo foo1.o foo2.o .. global_array.o -lfoo -lbar
I presume it is not important to recompile global_array if you
recompile pieces of the program *WITHOUT* linking as you didn't
rebuild the whole thing, and it will be recompiled when you do
a full build.
