Tim Northover 17d76dc72c ARM: disable emission of __XYZvfp in soft-float environment.
The point of these calls is to allow Thumb-1 code to make use of the VFP unit
to perform its operations. This is not desirable with -msoft-float, since most
of the reasons you'd want that apply equally to the runtime library.
