Hi,
      I have added support for gcc-4.5 and eglibc-2.13, in the retired tool-chain layer, and ran the build, against the latest poky master branch, and get the following warnings:

How can I fix this? 

Best regards,

The fix is very simple. The idea here is that a library from / which needs
something from /usr can have some problems while being on systems where /
and /usr are on different partitions and /usr can be unavailable at an
early stage. The obvious fix would be to move libgudev in /usr but before
doing this we need to be sure that nobody needs this in the early stages of
booting.

I would love to see this warning addressed.

That does not really matter; as things are if something is trying to use
libgudev before /usr is mounted, it will not work anyway, so moving it
under /usr/lib will not break anything that is not already broken per
se. But it could possibly break libgudev itself -- I think this is an
upstream bug that would be best pursued with the udev developers.
