Suricata

When configuring suricata v5.0.0 for cross compilation, the --target flag for the cargo command in omitted, thus the rust component of suricata (which builds libsuricata.a) is compiled for the build machine and not for the host

repro steps assuming suricata's compile tools and dependencies are met and a cross compiler is installed with $CC = arm-unknown-linux-gnueabihf-gcc:

# cd suricata-suricata-5.0.0
# ~/autogen.sh
# ~/configure --host=arm-unknown-linux-gnueabihf
# make

... notice the build command for libsuricata.a is missing the --target arm-unknown-linux-gnueabihf argumnent

cd ../rust && RUSTUP_HOME=~/.rustup \
    CARGO_HOME="~/.cargo" \
    CARGO_TARGET_DIR="~/suricata-suricata-5.0.0/rust/target" \
    ~/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/bin//cargo build --release  \
        --features " "
