One other nit, not blocking.

There should be no need for special casing clang vs gcc, since clang
supports gcc syntax in general.
https://clang.llvm.org/docs/AttributeReference.html#pragma-unroll-pragma-nounroll

The code could check for RTE_TOOLCHAIN_GCC/CLANG directly, and we
don't need a separate define passed from cmdline.

(idem in lib/vhost)
