People running ports-provided or hand-built clang 3.8.0 or higher on older FreeBSD's can use `-fno-movt`.  For clang versions 3.7.x and earlier, they can still use the old style `-mllvm -arm-use-movt=0`.

We'll fix the FreeBSD build system so it uses the right options for older and newer clang versions.
