PR #1509: Allow building when targeting WASI
Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1509
WASI is similar to emscripten, providing a syscall layer to WebAssembly focused on server side applications. There are some config knobs that are in place to allow building the repo for emscripten which also need to support wasi (as built with LLVM). Aside from that, there are still some features it supports less than escripten, for example related to signals, causing the build to be even more limited for it.
Merge ec9fa081609687035005dfdafd312754f31c3fbb into 861e53c8f075c8c4d67bd4c82217c57239fc97cf
Merging this change closes #1509
