Problem is that it's the compiler that is responsible for providing this 
directive in the intermediate .s prior invoking the assembler. And there 
is no assembler flag to pass through -Wa. If concern is ABI neutrality, 
then solution would rather be #if (_CALL_ELF-0) == 2/#endif. One can 
also make a case for

#ifdef _CALL_ELF
.abiversion _CALL_ELF
#endif

Cheers.
