Hard to say, but most errors encountered with gold are due to implicit 
linking. There is a lot of history here, and I'm boiling it down by 
saying this, but bfd effectively replicates a lot of the functionality 
of the dynamic linker, and this is one of the reasons cited for gold 
being faster than bfd (yet to be shown in 1:1 comparison by me) and 
being used to identify link time errors. Take a look at this old bug for 
a much more complete explanation:

Thanks for doing this. The readelf utility will explain the difference 
better than I can. :-)
