Hi Daniel

ARM hardfloat: fix struct return with float/double args

Fixes the case where the structure is not returned in registers.

I thought it was related to ret_2float_test

At least on Rpi I still have:

ret_2float_test... Segmentation fault


P.S. Compiled from a fresh git

The latter should be fixed by the one-liner I just committed.
