Resolve hard dependencies to x86 Linux

[powergee]

Currently, an x86 Ubuntu machine is required to access full functionality. This limitation arises because some internal dependencies rely on hardcoded x86 Linux functions, such as a modified implementation of [membarrier](https://github.com/jeehoonkang/membarrier-rs/tree/smr-benchmark) and [murmur3](https://github.com/kaist-cp/murmur3/tree/upgrade). As a result, this benchmark suite is less portable and hard to develop or test in other environments, such as AArch64 Linux or macOS. However, I believe these issues can be resolved with a minor effort by generalizing the affected crates to support additional environments.
