We had compiled all our v5 driver patches against clang v3.8 on  RH7.1 and didn't see a similar error. 
         "clang version 3.8.0 (trunk 249596) (llvm/trunk 249595)"

The '-Wno-shift-negative-value' option only got introduced after 3.6.0 clang release.  Pls. let us know if we need to support a minimum version of clang. We had asked this question earlier in the dpdk community, however we didn't hear back from anyone so far.

Thanks!
