Review comment:
no reason for it. I followed the approach for
[hexagon_link](https://github.com/apache/tvm/blob/a01b3890ec53ce8e288917c856af3cecc10a2aac/python/tvm/contrib/hexagon/hexagon.py#L65).
Maybe there was a reason there? but I don't think I need it for clang_plus. I
will address it in a follow up if nothing major was mentioned in the reviews.
