We're trying to guess the build system, not the target. When configuring cross-tools, it has always been necessary to specify the target triplet with --target. In a native environment, there should be numerous ways of determining the system ABI (if it matters) without invoking a C compiler (which is often not installed, leading to spurious problem reports from users).
