This test is skipped for hard-float, due to the case of passing 
arguments to a variadic function; it simply won't pass under 
-mfloat-abi=hard.

Jie, while you're at it, why not use the new __ARM_PCS symbol instead of 
__ARM_EABI__?
It more accurately marks the softfp conventions you're trying to assume 
here.
