[lldb-dev] The pre-built Windows LLDB binary has a dependency on an external python36.dll?

There has been a lot of churn in the build process for Python on Windows
over the past couple months.

Older versions included a pre-built Python DLL on Windows because of ABI
compatibility.  That issue is resolved, though, and I thought that was
already over by version 7 or earlier.

Because other compatibility issues, it was decided that the Windows version
could depend on 3.6+ while non-Windows versions might still rely on
slightly older versions of Python.

That said, I didn't expect an explicit dependency on python36.dll.  Please
file a bug.  I'll look through the revision history and see if I can loop
in the folks who've been making changes in this area.  I suspect it was an
unintended side effect.
