G71 and friends exist mainly as an alternative to CAM, to make hand-coding easier.
I don't know of any CAM system that generates G71 (which isn't to say that there aren't any). But I don't think much would be gained from doing so.
I am not familiar with any other CAM software for turning, but Fusion360 / HSMworks / Inventor CAM can do this.

The standard LinuxCNC turning postprocessor from the HSM library does not work without corrections (it uses Fanuc-style UVW for incremental offsets, which LinuxCNC does not understand). I don't know who added this post or why these corrections haven't been made in almost ten years.
G7X canned cycles are also not defined in this postprocessor, but you can add them by following the standard Fanuc turning postprocessor example. This will probably require verification and correction to match the LinuxCNC code-style. The cycles are defined in the following functions:
function onCyclePath()
function onCyclePathEnd()
