Subject: [PATCH] Disable libm on x86 without sse2

In <https://github.com/rust-lang/compiler-builtins/pull/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
<https://github.com/rust-lang/rust/pull/125016#issuecomment-2174572661>.

Disable Rust libm on x86 without sse2 to mitigate this.
