For testing i used buildroot because you not only need the whole cross-compilation toolchain with linker, ar etc but also some libraries compiled for the chosen target e.g. ncurses and zlib. buildroot provides it all already. And since November buildroot supports 390x arch.

I also tried with Debian x86 which provides s390x cross-toolchain but it stopped with termcap library not found :( It is even wore for Fedora 32. I used buildroot because i do not want to build the whole cross toolchain and libraries. Some cross-toolchains are available in Fedora, for example:

I can provide the buildroot package for crash-utility if necessary.
