  control: add ASCII parsers from amixer
ctlparse.c uses ceil() and so libm is need unrelated to soft- or hardfloat.

The softfloat option is intended to avoid floating-point code.

The root cause of this problem is that ctlparse.c uses floatin-point
calculations unconditionally; it should be rewritten to use integer
math, or to drop the float parsing if compiled with softfloat.
