The devguide advise to run `make -j`, why not, but in any cases between `make -j4` and `make -j` the warning:

    -----------------------------------------------
    Modules/Setup.dist is newer than Modules/Setup;
    check to make sure you have all the updates you
    need in your Modules/Setup file.
    Usually, copying Modules/Setup.dist to Modules/Setup will work.
    -----------------------------------------------

is invisible (gets on screen first, and get kicked real quick by the compilation lines).

This got me once, and I'm not alone: https://bugs.python.org/issue32335 (And I suspect we're more than just two).

I propose to make this stop the compilation, proposing two cases:

- You modified the file? Touch it so it gets seen as up to date by makefile
- You didn't modified it? Copy Modules/Setup.dist to Modules/Setup

Something like:

    $ make
    -----------------------------------------------
    Modules/Setup.dist is newer than Modules/Setup;
    check to make sure you have all the updates you
    need in your Modules/Setup file.
    Usually, copying Modules/Setup.dist to Modules/Setup will work.
    Or if you want to keep your modifications, touch Modules/Setup
    to skip this warning.
