But if you've read the ccache documentation you probably already have
that directory in PATH anyway. Does this patch provide a significant
advantage?

Having a default ccache directory in the makefile that's different from
the default documented in the ccache man page seems needlessly
confusing to me.
And see hier(7) and section 25.7.6 of the handbook for
why /usr/obj/ccache is a poor choice.
