Bug#990994: llvm-12-tools cannot be installed for a foreign architecture

[Michel Dänzer]

Package: llvm-12-tools
Version: 1:12.0.1~+rc4-1
Severity: normal

llvm-12-tools requires python3 packages from the same architecture. This prevents installing llvm-12-tools (and by extension llvm-12-dev) for a foreign architecture.

E.g. trying to install llvm-12-tools:i386 with aptitude gives:

 llvm-12-tools:i386 : Depends: python3:i386 but it is not going to be installed
                      Depends: python3-yaml:i386 but it is not going to be installed

See https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/9833/diffs?commit_id=af0fde955c518447ccd92134517b4e69308e10b2#3f46a9fa9651371b76f0894b75d719a4c5659642_44_45 for how I had to work around this in Mesa's upstream CI.

(In buster it was still possible to install llvm-*-dev packages for foreign architectures)
