build: prevent printing for unused variables for SDK
build: prevent printing for unused variables for SDK

Reduce some of the SDK configuration printing for non-Darwin
configurations.  This simplifies the output and SDK configuration.  The
parameter reduction simplifies the setup for cross-compilation.
