Looks OK from the Arm/AArch64 side. Will likely need approving by a llvm-libc reviewer.

Is this specific to software-floating point on Arm/AArch64? Are there other software-floating point targets that are affected? If so then may be worth making the conditions less target specific, or at least easier to extend.

Out of interest can you explain why fenv isn't supported? Is it just not implemented yet, or is there some fundamental reason why it can't be done. I know not all software floating point emulation emulates the environment.
