New build scripts can crash even in -no-stop

[Robert P. Goldman]

A failure in SBCL caused make-all-no-upgrade-no-stop to crash, which should never happen:

Now starting sbcl, loading the script support, loading ASDF from source, then exiting...

I'll try to fix the bug in ASDF/ACTION, which I think is relatively trivial.

But I don't know why this should cause the minimakefile scripts to crash. that should never happen if I ask for no-stop, and never happened before minimakefile, AFAIK.

[Faré (fahree)]

Maybe minimakefile should use cl-launch to dump an image while asdf is in working state, so breakage of asdf (which is likely to happen during development) doesn't stop the test system from working? The downside is having to rebuild that binary whenever there are changes in tools/ or its dependencies.

In this case of test-all-no-upgrade-no-stop, this looks like a failure of without-stopping...

[Faré (fahree)]

That was a bug in cl-scripting 0.1's without-stopping, that failed to prevent stopping at the first failure.

I fixed it in cl-scripting 0.2, that asdf-tools is now using. I also added a test suite for cl-scripting 0.2 to prevent regression.

I also added more information on debugging in the README.

I also made the make system create a standalone asdf-tools executable when you first use it, so that you can build asdf-tools when asdf is in good shape, and use it to test asdf even when asdf is in bad shape.
