Hi,

The deb13u3 package failed to build on a bunch of architectures on trixie:

https://buildd.debian.org/status/package.php?p=llvm-toolchain-22&suite=trixie

The ppc64el build failure is an upstream bug that's fixed in newer 
versions of LLVM, but for 22 we can just work around it (which Emilio 
did successfully for his deb12u1 upload 
https://people.debian.org/~pochu/llvm-bookworm.debdiff ).

The i386 invalid build-dep is related to libomp not being built on 
trixie (though it was later added to 19 after trixie's release). Emilio 
also fixed that in his bookworm upload.

The remaining two architectures (armel, s390x) not getting built are 
because of a bug in d/rules; when I switched from using llvm-libunwind1 
to libunwind-19, I missed the spot where the list of architectures for 
that package is generated for the build-dep.

I've prepared deb13u4 to fix all of those build failures. I've attached 
a debdiff between deb13u3 and deb13u4. If it looks good, I'll do a 
source-only upload to trixie.

(Emilio, you'll probably want to pull that libunwind fix into bookworm 
and possibly bullseye's llvm-toolchain-22.)

Thanks,
Andres
