Description
I got an internal compiler error when trying to cross compile a project with the latest nightly using xargo.
% rustc --version :(
rustc 1.24.0-nightly (1abeb436d 2017-12-27)
% RUST_BACKTRACE=1 xargo build :(
Compiling water-sensor-firmware v0.1.9 (file:///home/rnestler/proggen/projects/coredump/water-sensor/water-sensor-firmware-rs)
error: internal compiler error: /checkout/src/librustc_metadata/cstore_impl.rs:131: get_optimized_mir: missing MIR for `DefId(7/0:8 ~ cortex_m_rt[efa4]::lang_items[0]::start[0])`
note: the compiler unexpectedly panicked. this is a bug.
note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports
