This is a follow-up to https://bugs.debian.org/1114980 ; Please enable
libunwind for s390x, it is required for compiler-rt.
https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/blob/b8109f1e0c0b23f347df0d3362c0910726acab57/debian/rules#L616
libunwind has been supported on SystemZ since llvm 15:
https://github.com/llvm/llvm-project/commit/364c5023d2ce1617c706b185892ddfaa2fd4d166
For me, it would be great to have this fixed for llvm-toolchain-snapshot as
well. Perhaps other users would appreciate backporting this fix to -20 and
before. If you want additional bugs filled for those versions, let me know and
I'll do so.
Here's a simple patch:
