Description
This is perhaps more of a question or a "release management" issue, perhaps even "documenting the latter".
In my quest to continue to have rust buildable & installable in NetBSD's pkgsrc system, I've now come to rust 1.81.0.
The package has an option to either build with an external LLVM (and libunwind) or with the embedded version of at least LLVM
in the rust tarball.
When going from rust 1.80.1 to rust 1.81.0 I find that the rust compiler no longer builds with an external LLVM 17.x.
The last time a bump in the requirement for an external LLVM happened was in the 1.79.0 release.
My question is whether someone missed bumping the requirement in the rust release notes for 1.81.0, or whether
the errors I'm seeing while trying to use an external LLVM are of my own or "our own" doing. The errors start with
[ 29%] Building CXX object COFF/CMakeFiles/lldCOFF.dir/CallGraphSort.cpp.o
[ 30%] Building CXX object MachO/CMakeFiles/lldMachO.dir/Arch/ARM64Common.cpp.o

For some reason the build appears to want to build LLD.
Did someone not test building with an external LLVM 17.x? Does rust now from 1.81.0 in fact need an external LLVM >= 18?
