I pushed my changes based on QEMU softfloat, with all your patches added
and slightly adjusted because QEMU softfloat uses different data type names.

Currently all trigonometric and logarithmic functions use native
c-library functions. (QEMU does not have any)

I tested it quickly with few Amiga demos that use FPU. (mainly basic
operations like fmove/fadd/fsub/fcmp/fmul/fmdiv etc.. used)
