They are not available on anything except very new Linux distros.
Forget RHEL 6.x / 7.x. I'm fairly sure not 8.x either.
RHEL/OL 9.x could an example of the earliest that would work to build without these imports.
And that's just for building, even current 9.1 doesn't have sufficiently working runtime libs.
There should be a fix for that in 9.2 .. 

 Ubuntu 22.04 is however known to be OK.

Yes, a runtime thing. An implementation System Property needs to be set.
