feature rdseed fails to build on x86

[jonassmedegaard]

Building feature rdseed or --all-features fails on 32-bit x86:

error[E0432]: unresolved import `core::arch::x86::_rdseed64_step`
  --> src/entropy.rs:58:6
   |
58 |     use core::arch::x86::_rdseed64_step as rdseed;
   |         ^^^^^^^^^^^^^^^^^--------------^^^^^^^^^^

   |         |                help: a similar name exists in the module: `_rdseed16_step`
   |         no `_rdseed64_step` in `core_arch::arch::x86`

Does this happen even after

$ rustup target install i686-unknown-linux-gnu

$ cargo build --target=i686-unknown-linux-gnu

also of course make sure you have

$ sudo apt install gcc-multilib

[jonassmedegaard]

It happens on official Debian builds, which uses neither rustup nor gcc-multilib.
