Rather than messing with clippy attributes, just disable it in CI for now. Though this should be fixed properly by updating the |

Updated libm |
This is a continuation/fix of 018616e. In that commit, we made it add the math functions to all platforms (except apple-targets and windows), and use `weak` linking, so that it can be used if the system doesn't have those functions. Didn't notice `mod math` was behind another set of `cfg`, so removed it as well here.
The solution is not pretty, but not sure why we still get clippy warning from one of the files in `libm` even though we use `allow(clippy::all)`

Oops sorry for the noise. I accidentally tapped a button when scrolling on mobile. Hopefully I undid my mistake. |

In <rust-lang#594>, symbols for the Rust port of libm were made always weakly available. This seems to be causing problems on platforms with ABI issues, as explained at <rust-lang/rust#125016 (comment)>. Disable Rust libm on x86 without sse2 to mitigate this.
