Looking at the code, it seems just Name, Description and Version are
required. Everything else is assumed to be empty if the field isn't
there.

No, absolute paths are fine. However, the advantage of using the
variables is that you can override them if necessary.

pkg-config --cflags --define-variable=prefix=/foo bar

The other reason people typically use the variables is because
autoconf is already substituting them, so you get the flexibility
basically for free if you're using the autotools.
