[yocto] prelink-cross project update

[Mark Hatle]

The prelink-cross project has been updated with a number of recent commits. 
Each of these commits has been test with a Yocto Project target build and the 
internal test suite for: qemux86, qemux86-64, qemuppc, qemumips and qemuarm.

Note, due to various issues I was unable to validate the x32 ABI.
