@rlyerly I'm going to test it for another day or two, but I'll try to put together a pull request for at least the ARM changes.

Additional note: requires modifying `arch/aarch64/bits/float.h` in `musl` (replace every field except `DECIMAL_DIG` with values from `arch/arm/bits/float.h`.

I'll try to do so as soon as I can -- currently a bit tied up with coursework and prep for my M.S. defense. May be sometime next month before...
