Linking the standalone udev fails due to the missing librt when using
a more recent GCC toolchain to compile the package. It seems in earlier =

versions of the GCC toolchain librt comes in from a different library udev =
is =

linked against.

How to fix it? Adding a patch to its buildsystem to force the librt when =

linking udev? Or more simply with the following approach?

diff --git a/rules/udev.make b/rules/udev.make
index dcdf79c..735c1c2 100644
