Zhao Zhili ea3d21c349 tests/checkasm: Add partial support for wasm
WASI mssing signal and siglongjmp support. This patch workaround
build error and add simd128 flag. Please note that many tests use
large array on stack, so you need to increase the stack size when
build checkasm, e.g., --extra-ldflags='-Wl,-z,stack-size=10485760'
