Have a try on my machine, but looks like it works for me (./configure 
--cc=clang).  version is

clang version 3.8.0-2ubuntu3 (tags/RELEASE_380/final)
Target: x86_64-pc-linux-gnu
Thread model: posix

Looks like "-Werror,-Wtypedef-redefinition" was not used by default. 
After I add them to extra_cflags, e1000e can still build successfully.

Is there anything I missed?

Thanks
