wasm: add -flto option

Browse source 
Clang 16 of emsdk does not support `-flto=0` option.
so I temporarily add -flto option.

clang-16: error: unsupported argument '0' to option '-flto='

em++: error: '/home/junsu/dev/os/emsdk/upstream/bin/clang++ -target wasm32-unknown-emscripten -fignore-exceptions -fvisibility=default -I/home/junsu/dev/os/emsdk/upstream/emscripten/cache/sysroot/include/SDL --sysroot=/home/junsu/dev/os/emsdk/upstream/emscripten/cache/sysroot -Xclang -iwithsysroot/include/compat -O2 -Werror -fno-unroll-loops -g3 -flto=0 -c /home/junsu/dev/os/emsdk/upstream/emscripten/system/lib/embind/bind.cpp -o /home/junsu/dev/os/emsdk/upstream/emscripten/cache/build/libembind-rtti/bind.o' failed (returned 1)
