Building a cross compiling toolchain is a good exercise, but if you need to have a suite of tools/libs, check out llnl's spack. Spack automates building compilers/toolchains/libs from source, has hundreds of package definitions, and supports cross compiling. Kinda like Gentoo, but usable on any Linux/Mac platform. http://spack.readthedocs.io/en/latest/basic_usage.html http://spack.readthedocs.io/en/latest/basic_usage.html
