I had the same problem today trying to build llvm-devel and clang-devel
(clang 3.5) on a wandboard.  The actual problem is "llvm-build: error:
invalid native target: 'armv6' (not in project)"; it leads to the
dependencies not being built.

Try copying the attached file into the files directory of *both* the
llvm and clang ports, replacing the same-named file already there, then
do a make clean and start the build over.
