Hi Lianbo,

sorry for the late response, just came back from vacation.

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.

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

Regards
Alex
