Some pythons are configured to set platlib somewhere outside of their
sys.prefix. It's important that we at least use some reasonable
default for LLDB_PYTHON_RELATIVE_PATH even in that case, because
even if the user overrides it on the cmake invocation, cmake will
still be called without the override in order to build tablegen.
