They are not always compatible but I don't see any way to detect it in the current system and it is possible to have code compiled with AndroidEabi and AndroidEabiHF inside the same application if all API crossing the ABI boundaries are annotated with attribute((pcs("aapcs"))).

The android platform libraries are soft float with all API with floating point argument is marked with attribute((pcs("aapcs"))) so user libraries can be hard float (not sure how well it works)
