When the compiler does work, we immediately `try_compile` the ABI detection source. In the common case that both steps work, we gain no useful information from the first one and the work was wasted. Re-order the checks to try the ABI detection first. If it works then assume the compiler works and skip the dedicated check. If the ABI check fails then proceed with the normal test for a working compiler so the diagnostic can be shown as before.
