SoH does not use the authentic libultra implementations for math functions such as cosf, nor emulate intrinsics

OoT did not use any part of what would be considered the C standard library. Instead, libultra provided functions that acted the same, such as `cosf` and `sinf`. Additionally, OoT utilized intrinsics for `fabsf`, `sqrtf`, and `sqrt`.

As it currently is, we do not utilize neither libultra's implementation of math functions, nor emulate the hardware's implementation of intrinsics. Instead, we utilize whatever C standard library's implementation of them. This is probably not inaccurate, but it _is_ inaccurate, Accordingly, we should either document this, or provide a way to get the accurate behavior. Additionally, there may be a task for libultraship to provide accurate libultra implementations for these functions.
