In order to use the switchless feature of the SGX, the app binary needs to be linked with the following flags.
``` -Wl,--whole-archive -lsgx_uswitchless -Wl,--no-whole-archive ```` Noted that there is currently no proper way to pass custom link flags to all the binaries in a cargo project. As such, the `link_args` macro need to be set for each of Rust files with `main` methods.
