Fixed false positives in Emscripten detection. (#35) Almost all languages targeting WebAssembly create imports from "env" module by default, which means that Emscripten was being detected even when it wasn't used. Use "_emscripten_memcpy_big" as a signal, since it's imported in all WASM modules produced by Emscripten, even as simple as: EMSCRIPTEN_KEEPALIVE int main(int argc, const char** argv) { return 0; } Signed-off-by: Piotr Sikora <piotrsikora@google.com> 2018-12-05 18:01:52 -08:00			`(import "env" "_emscripten_memcpy_big" (func $_emscripten_memcpy_big (param i32 i32 i32) (result i32)))`
