Duplicate of #240

Hmm OK, I will close this if that is the case. I thought #240 was only about docs for dependent crates failing to build, not for the gdal crate itself.

Yeah, I think it's the same root cause -- the gdal build script trying to call GDALVersionInfo because it doesn't realize it's running on docs.rs.
