From the licensing point of view, they seems to use the SoftFloat-2a
license, so that should be fine.
Personally I am fine adding general trigonometric functions to
softfloat, that might help other targets like x86 which uses the math
functions from libm and thus have different behaviour/precision
depending on the host.
The question is more how m68k specific are those trigonometric
functions. If we can have a way to implement them as generic
trigonometric functions reusable by other targets, I am all for it. If
not that code would probably be better in target/m68k.
