Cannot link absl with Standalone Wasm module

[bianpengyuan]

When using bazel compile Stand alone Wasm module with absl, emscripten compiles shared:ERROR: STANDALONE_WASM does not support pthreads yet. We have to apply the following patch to work around this:

Can absl bazel build add another platform to support Standalone Wasm?

Effort to add wasm as a cpu option to bazel: bazelbuild/platforms#12

This is done I believe:
