Dear Maintainer,
The source package llvm-toolchain-19 FTBFS on a current Trixie system running
on ARM64.

Digging into the control file, we found this patch:
https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/commit/b13a5e5005bcc0da6bde1a2331d82c14e79fd9d1
This seems to break the build-dependencies for an ARM based build. The patch
ignores the warning described a few lines below regarding the constraints of
the alternatives.
Below is a small patch which fixes the issue for us.
