Description
Trying to build a crate that depends on protoc. When cross-compiling, I have to add Cross.toml:
[build]
default-target = "armv7-unknown-linux-gnueabihf"
pre-build = [
"dpkg --add-architecture $CROSS_DEB_ARCH",
"apt-get update && apt-get --assume-yes install protobuf-compiler:$CROSS_DEB_ARCH",
]
How can I add that configuration when compiling with this layer?

Research direction
Start by reading how this Yocto layer integrates Rust cross-compilation and the Cross.toml configuration shown in the issue. Determine where the layer passes build settings to crates; done means users can supply a default target and pre-build commands such as the protobuf compiler setup when compiling with the layer.
