Re: [Xen-devel] [PATCH 35/46] Use just PREFIX to reference the path in Paths.mk

$prefix comes from autoconf/automake, PREFIX is used in xen source.
Since the variable SYSTEMD_DIR= is expanded, $(prefix)/something would
expand to /something because prefix= does not exist anymore once this
whole series is applied.

But as stated in an earier reply, maybe we expand to lowercase variables
in Paths.mk and assign to our uppercase variables as needed. Then this
patch can be dropped.
