            Bug ID: 40165
           Summary: Add multilib clang / llvm Debian packages to enable
                    cross compilation for 32-bit from 64-bit
           Product: Packaging
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: deb packages

I was trying to cross compile 32-bit Mesa in 64-bit Debian testing some time
ago, and while it used to work well in the past using i386 llvm and clang
dependencies with gcc-multilib and related tools, at some point it stopped
working because of packaging changes.

Namely, libclang-8-dev:i386 became non co-installable with gcc-multilib
g++-multilib. It boils down to libc6-i386 conflicting with libc6-amd64:i386.

Debian developers said, they can't do anything about that change, and
recommended for example splitting llvm/clang packages into regular and multilib
variants.

See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=890801 for details.

Can you please make such kind of split for packages in apt.llvm.org to enable
cross compilation?
