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. I use clang-3.6.2. You are right there is no official requirement in doc/guides/linux_gsg/sys_reqs.rst. Opinions about minimal version to support?
