I second this - I also faced it. I think this is not a problem with a 
ports but rather with a build as correspondent files can be found in 
/usr/obj under /usr/obj/usr/src/tmp/usr/lib/clang/3.8.0/lib/freebsd/. 
Looks like this files are compiled during build but taken from 
compilers's directory. Linking 'em to the target directory makes build 
succeed.
