Actually, when I try to get rid of it I get issues with srcdir being
recursively defined.

And in fact, VPATH is defined by Makefile.global when the Postgres build
is a VPATH build, and unrelated to the module's build setup.

So I think it's probably best to leave this as it is unless you can
suggest an easy fix.
