8c9dd24a6fbf9ed10ae81f9fa0bc2168558a9700 by Abseil Team <absl-team@google.com>:

Improve WebAssembly detection when using Bazel.

Unfortunately, the --cpu values are not standardized, and both
--cpu=wasm and --cpu=wasm32 are used in the wild. Most notably,
Emscripten's Bazel rules use --cpu=wasm, which was missing.

While there, add support for @platforms//cpu:{wasm32,wasm64}.

This change adds a dependency on @bazel_skylib, which requires
adding the following http_archive() rule to the WORKSPACE file:

  http_archive(
    name = "bazel_skylib",
    urls = ["https://github.com/bazelbuild/bazel-skylib/releases/download/1.2.1/bazel-skylib-1.2.1.tar.gz"],
    sha256 = "f7be3474d42aae265405a592bb7da8e171919d74c16f082a5457840f06054728",
  )
