Yeah, the new HEAD codebase assumes a newer version of Clang from HEAD, which is kinda silly. I mean, the only reason the new Clang is needed is because of this one specific warning option in the bxe module -.- You'd think you could solve this by doing make kernel-toolchain or make buildworld (to get a system compiler from the HEAD world), but no: both targets fails because the header "yacc.h" cannot be found! In short: head cannot be upgraded into release system without a 3rd party Clang installation. I've heard rumors that this was fixed in a later HEAD revision, but I am not sure which ... and this info would not help me anyway, since I am not proficient enough to merge HEAD into the branch.
