Most build systems distinguish a failed build from a failed test run,
but make.sh has a hard time doing that because of the conflation of the two.
The whole regression suite should be run if you want to ensure a good build,
so that would be a good time to test contribs. Not only that, with ASDF
we obscured a ton of style-warnings, we lost sandboxing of input files,
the ability to use --evaluator-mode, automatic generation and cleanup of
scratch pathnames, and automatic sb-sprof profiling.
So convert contrib tests to use WITH-TEST except some that gave me trouble.
This makes the output a ton more readable, and makes bisection on seldom-used
configurations quicker, not to mention that SB-RT is very lame anyway.
And there is quite literally less code to maintain now. Go figure.
