I'm not sure if this is related to your issue, but Xargo hasn't been required for Cortex-M development for a while. Try installing a pre-compiled core library using Rustup instead:
$ rustup target add thumbv6m-none-eabi
And then you should be able to just build using Cargo:
$ cargo build --target thumbv6m-none-eabi
xargo 0.3.12 cargo 1.30.0-nightly (2fb77a49b 2018-09-07) cortex-m-quickstart: 0.3.4 target: "thumbv6m-none-eabi"
Compiling for any target with thumbv7 seems to work fine
