Comment (by kencu):

 looks like `llvm` added an option to disable the bindings
 <https://reviews.llvm.org/rL332816> and <https://reviews.llvm.org/D42026>
 that we can use to turn them off.
 {{{
 LLVM_ENABLE_BINDINGS=OFF
 }}}

 It would seem most consistent to turn them across the board (they are not
 built in the buildbot versions of these ports, as the system tests for
 `go` and `ocaml` to see if the bindings should be built, and the buildbots
 don't have these installed during their clean builds.

 I have to figure out which versions of `llvm` support this configure flag
 to turn the `go` bindings off. Unfortunately not all of them, no doubt, so
 there will be some inconsistency in the `llvm` ports wherever this break
 comes.

 I don't know if there is anyone out there who would expect the bindings to
 be built. That would require new dependencies for `llvm` on `go` and
 `ocaml`, but only on 10.10 and up where `go` works correctly -- I hate to
 bring in yet another variant to these ports, as they have too many
 variants already.
