Comment (by catalyst):

 I think there are packages in Ubuntu that have specific clang version
 numbers, like clang-format-9 on Bionic? That's how I was getting 6.0 on
 Xenial (which otherwise defaults to 3.8).

 Ubuntu installs them with executable names like clang-format-6.0, so we'd
 have to parameterize how our tools invoke clang-format.
