Bug#1102278: coinstallation failure of various llvm-toolchain-20 packages

[Helmut Grohne]

Package: libc++-20-dev,libc++1-20,libc++abi-20-dev,libc++abi1-20,libclang-rt-20-dev,libmlir-20,libmlir-20-dev,liboffload-20,libomp5-20,libpolly-20-dev,libunwind-20,libunwind-20-dev
Version: 1:20.1.1-1~exp1
Severity: serious
User: debian-qa at lists.debian.org
Usertags: fileconflict

The named packages fail to coinstall despite explicitly declaring that
capability via Multi-Arch: same. Most of them install
architecture-dependent files to architecture-independent filenames below
/usr/lib/llvm-20/lib. Please either move those files to multiarch
locations or remove the Multi-Arch: same annotations.
