Yes, the in-tree file should be a common base.

I don't understand the logic.
When packaging a library using autotools, you are setting some options to 
"configure" script which are not saved elsewhere than in the spec file, right?
Why it wouldn't be the same here (options in spec file)?

I'm speaking about lib/librte_eal/linuxapp/igb_uio.
I think you are building it and it would fail if you no kernel header 
installed.
