Hi; this commit seems to have broken my static build.
Previously configure did not include libudev in the link
for a static build (there is no libudev.a, at least on my
system). Now it does, and then the link fails with
/usr/bin/ld: cannot find -ludev

This is the old code, which doesn't enable libudev for
static builds.

I'm not very confident about reading meson.build logic, but it
looks like this trusts meson/pkg-config to tell it about
whether it can do a static link against this library,
which doesn't work on my system, at least. (Ubuntu 18.04.4).
