What seems to be the source of the problem:
rust-osdev/cargo-xbuild#69

[ascjones]

I think caused by rust-lang/cargo#8192.

I'm currently investigating this. In the meantime it will work using an older nightly release e.g.

cargo +nightly-2020-03-11 contract build

Note that you may need to install rust-src for that with rustup component add rust-src --toolchain nightly-2020-03-11
