Bug#1115194: libllvm19: should be multi-arch, get removed by merge #168

[Ingo Saitz]

Package: libllvm19
Version: 1:19.1.7-5
Severity: normal

Seems like the merge

https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/merge_requests/168

dropped Multi-arch: same from libllvm19 by fuzzy matching
libllvm at LLVM_VERSION@ with liboffload- at LLVM_VERSION@. The later is only
available in llvm-toolchain-20. The same thing has happened to
libllvm18, too.

Since libllvm19_1%3a19.1.7-6_amd64.deb still looks perfectly installable
for multiple architectures, please re-add Multi-arch: same for the
package in llvm-toolchain-19 and -18. Otherwise this breaks multi-arch
support for a number of dependant packages like mesa.


I compared the changes in merges #164, #167 and #168, the following
packages were changed in debian/control (and debian.control.in,
respectively):
