Dear Maintainer,

Package is marked as `Multi-Arch: same`, implying that packages with
different archetictures can be co-installed, however it contains binary
(shared library) files in non-multiarch location
(/usr/lib/llvm-19/lib/libc++.so.1), and fails to co-install.
Please either move files to multi-arch locations (preferred) or mark package as
non-multi-arch.
Same applies to other shared-library packages from
llvm-toolchain-{11,13,14,15,16,17,18,19}, such as libc++abi1-19,
libomp5-19, libunwind-19,... (thus affecting everything from
oldoldoldstable to sid)
