Compile openssl with emscripten

[Sunghyun Park]

Hi, all.

I'm trying to compile openssl (with no-asm option) for webassembly, but facing bunch of errors which are mostly link failures due to the lack of emscripten-compiled libraries.

For example, my compilation crashes with 'fatal error: 'stdatomic.h' file not found.' or 'undefined reference to ...'. 

Any advice or share of experience will be greatly appreciated!

Thank you.
