SYNOPSIS
\t$NAME [-h|--help] [toolchain|build|qemu|test|all]

DESCRIPTION
\tCross compile using a cross toolchain.

\tYou MUST define the following variables before running this script:
\t* TARGET:
\t\tx86_64
\t\taarch64 aarch64be (bootlin)
\t\taarch64-linux-gnu aarch64_be-linux-gnu (linaro)
\t\tarm-linux-gnueabihf armv8l-linux-gnueabihf arm-linux-gnueabi (linaro)
\t\tarmeb-linux-gnueabihf armeb-linux-gnueabi (linaro)
\t\tmips32 mips32el (codespace)
\t\tmips64 mips64el (codespace)
\t\tppc (bootlin)
\t\tppc64 ppc64le (bootlin)
\t\triscv32 riscv64 (bootlin)
\t\ts390x (bootlin)

OPTIONS
\t-h --help: show this help text
\ttoolchain: download, unpack toolchain and generate CMake toolchain file
\tbuild: toolchain + build the project using the toolchain file (note: remove previous build dir)
\tqemu: download, unpack and build qemu
\ttest: qemu + run all executable using qemu (note: don't build !)
\tall: build + test (default)

EXAMPLES
* Using export:
export TARGET=aarch64-linux-gnu
$0

* One-liner:
TARGET=aarch64-linux-gnu $0"
}
