A two minute check into Makefile shows that the recursion is
implemented via $(MAKE), which is the recommended way to do it. It's
impossible to "forget" $(MAKEFLAGS), since the docs clearly say that
it is always exported unless explicitly unexported.
The *real* reason why it rebuilds GIT-VERSION-FILE is that the
Makefile says '-include GIT-VERSION-FILE', and uses the version info
to decide some parts of the build process. (It'll also do a similar
thing with the $CFLAGS detection code.) Since this influences the
actual commands executed, it seems sensible to run them even under
'make -n'.

From somewhere near the top of Makefile, which is definitely a
recommended read:
# Define NO_CURL if you do not have libcurl installed. git-http-pull and
# git-http-push are not built, and you cannot use http:// and https://
# transports.
Next time please take the time to investigate at least a little bit
into your "issues" before starting to cry foul.
