If the environment is considered to be the triple component as a whole, so, including the object format, if any, and if that is the intended behaviour, then the loongarch64 function `computeTargetABI()` should be changed to not rely on `hasEnvironment()`, but, rather, to check if there is a non-unknown environment set. Without this change, using a (ideally valid) target of loongarch64-unknown-none-elf, with a manually specified ABI of lp64s, will result in a completely superfluous warning: ``` warning: triple-implied ABI conflicts with provided target-abi 'lp64s', using target-abi ```
