WebAssembly target

[yurydelendik]

I'm entertaining the idea of using clouldabi in WebAssembly envirnment. I forked the project at https://github.com/yurydelendik/cloudlibc and it works for simple example now. So far I identified following items that will be nice to upstream:

• [ ] allow crt1.o output (current is crt0.o)
• [ ] use #define LG_PAGE 16 for wasm
• [ ] disable vDSO logic
• [ ] add/stub logic for fenv
• [ ] decide what to do with auxiliary vector

If there is an interest in accepting to above changes, I will be willing to submit pull requests.

Indirectly. My efforts purely experimental and pointed to compiling/running existing C code. The wasmtime is a user of the compilation output.
