   I happened to give this a try and built a drop-in replacement for `std`, see https://github.com/yaxitech/incubator-teaclave-sgx-sdk/commit/41ae223d6458db488b938927015c643720b416ef. I can build an internal project that depends on things like `reqwest` just fine with the resulting sysroot. The only patch I have to apply is to remove the cdylib crate-type from hyper.
   
   Of course the result cannot actually run as syscalls get linked in from glibc via the `libc` crate, heavily used by `mio` and `socket2`. Such crates either still have to get adapted "[sgx-world](https://github.com/dingelish/sgx-world)-style" or be provided with a `libc` replacement / extension that builds on ocalls or whatever is appropriate for the required syscall functions.
   
   (By the way, this is basically a duplicate of #75.)
