Patch by Robert Scheck for xfce4-sensors-plugin >= 1.0.0, which adds the missing (former implicit) linking to libm. It corrects the typo with the missing backslash in the Makefile.am as well to get linking to libxfce4panel and libsensors again. As implicit linking can be dangerous, Fedora has changed this behaviour.
