Crate tectonic_cfg_support 

This support crate helps deal with CARGO_CFG_TARGET_* variables. When cross-compiling with a build.rs script, these variables must be used instead of constructs such as cfg!(target_arch = ...) because the build.rs compilation targets the build host architecture, not the final target architecture.

For more information, see the documentation on:

• cargo environment variables
• conditional compilation
