I take that back, kotlin now builds with OpenJDK 17 and is on track to
migrate to testing.

This comes at a price though, besides my sanity I had the sacrifice the
Android support (the Android dependencies still build with OpenJDK 8) 
and
the -Xuse-javac option which hasn't been updated for OpenJDK 17 yet [1].

It isn't extensively tested yet but the resulting package is good enough 
to
rebuild itself.

The next hurdle is to enable the Kotlin DSL in Gradle. I've packaged the
version of gradle-kotlin-dsl that came with Gradle 4.4 but it doesn't 
work.
When Gradle encounters a .kts file an obscure error is thrown
(NoDescriptorForDeclarationException: Descriptor wasn't found for
declaration SCRIPT). I have no idea how to fix this, and I now think 
this
is a dead end anyway. gradle-kotlin-dsl uses internal Gradle APIs that
changed in Gradle 5, so if we use the Kotlin syntax to upgrade Gradle,
it'll break immediately and we'll be unable to rebuild Gradle.

The solution I think is to upgrade Gradle to the first version with the
Kotlin DSL source code merged, which is Gradle 5.3. I leave that to 
someone
else.
