So in your case, the host and target are both x86, so it picks out of
the dictionary the empty string, which was supposed to indicate no
subdirectory, and misinterprets that as "we don't know about this pair
at all".  Sounds legit enough...

_HOST_TARGET_TO_CL_DIR = {
...
    ("x86","x86")      : "",
...


Do you want to submit a pull request?  If not someone else can do it
easily enough, I guess.
