Gem::TargetRbConfig

A TargetConfig is a wrapper around an RbConfig object that provides a consistent interface for querying configuration for *deployment target platform*, where the gem being installed is intended to run on.

The TargetConfig is typically created from the RbConfig of the running Ruby process, but can also be created from an RbConfig file on disk for cross- compiling gems.
