Well basically udev is completely broken on sparc when compiled with
LTO and "gold" linker.
It's not an udev fault. Increasing rootdelay won't help because udev
built this way can't even parse it's command line.
The experiments has shown that building it with the bfd linker or
without LTO produce a working udev.
