It's not in any automatic build right now, the source and discussion
is at https://github.com/openscad/openscad/pull/2079

It's in a forked repo. Github suggests the following commands
to get the code based on master which currently will create
a code conflict:
If you have an affine description of the 2D polygon, you can always use a
sweep() to emulate any linear_extrude operation. As far as I know current
sweep implementations don't support 2D polygons with holes. But in this case
you still can sweep the primitives and do all the Boolean stuff in 3D.
