The wasi-sysroot toolchain contains both a sysroot for wasi and a compiler-rt for clang. That makes it impractical to use as a bootstrapped sysroot for wasm32-wasi builds of Spidermonkey. We thus split the toolchain in two, one for the compiler-rt and one for the sysroot. Ideally, the compiler-rt one would avoid building clang/llvm the same way the sysroot one does, but that leads to a case of chicken-and-egg, because the compiler-rt is needed to build the clang toolchain. Eventually, the clang build would be split from the addition of the compiler-rt, but we're not there yet. Differential Revision: https://phabricator.services.mozilla.com/D122402
