Hello.
I would like to compile a example - Hello project.

mhanusek@EtHanusek:~/work/VersionControl$ cargo new --bin hello
Created binary (application) hello package

file ./helo/.cargo/config:

[build]
target = "armv7-unknown-linux-gnueabihf"

[target.armv7-unknown-linux-gnueabihf]
linker = "/opt/etos/1.2.1/sysroots/x86_64-etossdk-linux/usr/bin/arm-etos-linux-gnueabi/arm-etos-linux-gnueabi-gcc"

Compiling:

mhanusek@EtHanusek:~/work/VersionControl/hello$ cargo build --target=armv7-unknown-linux-gnueabihf

error: aborting due to previous error

error: could not compile hello.

To learn more, run the command again with --verbose.

What's wrong?
