----------------
My impression, after reading the problem description, is that the actual issue
is that we're using `-internal-isystem` for the HIP SDK includes , not that we
add the include path to them.
Instead of trying to guess whether we happen to match some hardcoded path where
we think the standard headers may live, I'd rather use `-I` or its internal
equivalent, if we have it. Hardcoded paths *will* be wrong for someone. E.g.
I'm pretty sure `/usr/anything` is not going to work on windows. Of for our
internal builds.
