Several distros have been dropped since the last time we bumped the
minimum required CLang version.
Per repology, currently shipping versions are:
RHEL-8: 10.0.1
Debian Buster: 7.0.1
openSUSE Leap 15.2: 9.0.1
Ubuntu LTS 18.04: 6.0.0
Ubuntu LTS 20.04: 10.0.0
FreeBSD 12: 8.0.1
Fedora 33: 11.0.0
Fedora 34: 11.1.0
With this list Ubuntu LTS 18.04 is the constraint at 6.0.0
An LLVM version of 6.0.0 corresponds to macOS XCode version of 10.0
which dates from Sept 2018.
