make: avoid problems with mv aliases

Make fails to update .xcompile in case there is an mv alias preventing
    silent overwrites of existing files. To avoid ambiguity, invoke mv
    from standard location.

While we are at it, drop the code creating a unique .xcompile instance
    before copying it into destination: this was done for the case of
    running multiple independent make processes in parallel, but there is
    a problem with this approach with multiple processes copying their
    unique copies into the same destination file.

The tool running multiple make invocations in parallel should
    explicitly invoke xcompile first.
