Comment:
When I am compiling for i686 is this actually a cross compile?

Setting up locally a bootstrap environment for i686 I get the same error message as Travis. If it were a cross-compile it would show up in the call to the configure script. See: https://gitlab.com/tspiteri/gmp-mpfr-sys/-/issues/15. But building the project just with `cargo build --release` when change rooting into `master_dir` works just fine. Don't know what the issue is.
