I suspect that any target we have in tree but not in the default
list is liable to bitrot because nobody will compile test it
(and indeed nobody knows about it since it's undocumented).

That said, we could have an experimental-configs/ to go with
default-configs/, such that we allow --target-list=foo if
there's an experimental-configs/ file but don't default to
it (and we could even print a "warning, this is an experimental
target!" message if we were feeling friendly, and have an
--enable-experimental-targets options so buildbots could at
least compiletest them).

I'm not sure that's worth the effort at this point when we don't
actually have any targets in tree which aren't enabled by default,
though. (I did cross-check the old and new lists so this patch
isn't accidentally enabling a previously disabled config.)
