--- Comment #24 from Alexander Egorenkov <egorenar at linux dot ibm.com> ---
I finally figured it out and fixed buildroot.
This info is for posterity, in case somebody will have the same issue.
If i understood it correctly, then the problem was that buildroot
wrongly tried to build a native compiler on s390x host for s390 target instead
of a cross-compiler due to a problem is config.sub which is fixed by this path:

After fixing config.sub everything builds just fine and works great :)
I'm going to try to submit this fix to the config mailing list.
Best regard & thank you
