build tectonic_cfg_support

A build.rs support crate that helps deal with CARGO_CFG_TARGET_* variables. When cross-compiling, these variables must be used instead of constructs such as cfg!(target_arch = ...) because the build.rs script is compiled to target the build host environment, not the true target environment

The tectonic_cfg_support crate

This crate helps build.rs files deal with CARGO_CFG_TARGET_* variables. When cross-compiling, these variables must be used instead of constructs such as cfg!(target_arch = ...) because the build.rs script is compiled to target the build host environment, not the true target environment. This crate is part of the Tectonic project.

lib.rs:

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.
