(We may have discussed this on IRC).
If running "make" at top level does not cause any recompilation, but
running "make install" at top level does, then something is wrong
somewhere. Unfortunately I have no idea what it could be. It implies
that some dependency expressed in the Makefile changes when you run
"make install". I don't know how that could happen.
If I had a repeatable test case for this, I would start by running "make
-d install". That will generate huge amounts of output, but buried in
there somewhere will be the reason that make considers the target to be
out of date.
