wasi-sdk-8

Note: Path names within the wask-sdk tar archive no longer contain opt/wasi. This means that paths to WASI tools will all be shorter, but build scripts will need to be updated accordingly.

In this release, wasi-libc includes optimizations to avoid linking in command-line argument initialization code in programs that don't use command-line arguments (eg. `int main(void)), and similar to avoid linking in environment-variable initalization code in programs that don't access environment variables.

And, the wasi-sdk installation now includes common tools such as nm, ar, strings, and others.
