Bug#1004914: libclang-common-13-dev: /usr/bin/s390x-linux-gnu-ld: cannot find /usr/lib/llvm-13/lib/clang/13.0.1/lib/linux/libclang_rt.builtins-s390x.a: No such file or directory

[Nicholas Guriev]

Package: libclang-common-13-dev

Dear maintainer,

The package seems to be missing libclang_rt.builtins-s390x.a, compiler
runtime library, and so Clang is unable to produce useful binaries on
s390x platform. Can you please look at this error? This is especially
critical for C++ code with exceptions which require internal __cxa
routines.
