Subject: [PATCH 14/15] Makefile: support static-only builds

One of the problems with udev is that systemd cannot be built
statically[1].  With libudev-zero, on the other hand, no code changes
are required to be able to do a static-only build, only Makefile
changes.

With this change, it's possible to "make install-static" to do a
static-only build of libudev-zero.
