build for various targets - Burn

The burn-no-std-tests contains integration tests aimed to check no_std compatibility of burn, burn-core, burn-tensor and burn-ndarray packages.

Currently there is only a minimal test that checks if mnist model can be built with no_std. More tests should be added to check completeness.

The continuous integration (CI) should build with additional targets:

wasm32-unknown-unknown - WebAssembly
thumbv7m-none-eabi - ARM Cortex-M3
thumbv6m-none-eabi - ARM Cortex-M0+

Shell commands to build and test the package:


# install the new targets if not installed previously
rustup target add thumbv6m-none-eabi
rustup target add thumbv7m-none-eabi
rustup target add wasm32-unknown-unknown

# build for various targets 
cargo build # regular build
cargo build --target thumbv7m-none-eabi
cargo build --target wasm32-unknown-unknown
RUSTFLAGS="--cfg portable_atomic_unsafe_assume_single_core" cargo build --target thumbv6m-none-eabi

# test
cargo test
