@Emilgardis I'm not sure how desirable adding unstable features is, but this seems pretty important to testing cross-compiled libraries, so I've added it behind an environment variable ( The README mentions: ### Unstable Features
Certain unstable features can enable additional functionality useful to
cross-compiling. Note that these are unstable, and may be removed at any
time (particularly if the feature is stabilized or removed), and will
only be used on a nightly channel.
- `CROSS_UNSTABLE_ENABLE_DOCTESTS=true`: also run doctests. |

Allow values of 0, 1, so values other than `true` or `false` can be provided. `VAR=0`, `VAR=`, `VAR=-0`, or `VAR=false` will evaluate to false, while the rest will evaluate to true. Affects cross-rs#661 and cross-rs#721.

This partially addresses cross-rs#225. This only works on nightly, due to the use of the unstable feature [doctest-xcompile](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#doctest-xcompile) The relevant tracking issues are: - rust-lang/cargo#7040 - rust-lang/rust#64245 If the subcommand is `test` and the compiler is nightly, we provide the `-Zdoctest-xcompile` flag if `CROSS_UNSTABLE_ENABLE_DOCTESTS=true`.
