[PATCH] Makefile: remove redundant GIT-CFLAGS dependency from "sparse"

[PATCH] Makefile: remove redundant GIT-CFLAGS dependency from "sparse"

[Ævar Arnfjörð Bjarmason]

The "sparse" target needed the GIT-CFLAGS dependency before my
c234e8a0ecf (Makefile: make the "sparse" target non-.PHONY,
2021-09-23), but since then it depends on the corresponding *.o files,
which in turn depend on the correct header files, as well as on
GIT-CFLAGS. There's no need to re-state this dependency here.

A tiny redundancy fix for an already-in-master topic.

I _guess_ you could say that the `GIT-CFLAGS` dependency is redundant by
virtue of the `*.o` targets already depending on it.

But then, how much does it hurt? This late in the v2.34 cycle, aren't
there any issues that might be worthier of our attention and care?

Ciao,
