GCC changes the CC between the user-code and the builtins based on the value of `-target` rather than `-mfloat-abi`. When a HF target is used, the VFP variant of the AAPCS CC is used. Otherwise, the AAPCS variant is used. In all cases, the AEABI functions use the AAPCS CC. Adjust the calling convention based on the target.
