Re: Wow: Building the likes of devel/llvm16 now requires building rust first (when rust is out of date). . .

This needs to be fixed.  One massive compiler should not depend on another massive
compiler just in case something in the tool chain wants to make an HTTPS request.
Setting DOCS=off does not fix the dependency.

Here is my list of stripped-down devel/llvm17 options that still require rust

===> The following configuration options are available for llvm17-17.0.0.r4:
     BE_AMDGPU=off: AMD GPU backend (required by mesa)
     BE_WASM=off: WebAssembly backend (required by firefox via wasi)
     CLANG=on: Build clang
     COMPILER_RT=on: Sanitizer libraries
     DOCS=off: Build and/or install documentation
     EXTRAS=off: Extra clang tools
     FLANG=off: Flang FORTRAN compiler
     LIT=on: Install lit and FileCheck test tools
     LLD=on: Install lld, the LLVM linker
     LLDB=on: Install lldb, the LLVM debugger
     MLIR=on: Multi-Level Intermediate Representation
     OPENMP=off: Install libomp, the LLVM OpenMP runtime library
     POLLY=off: Polyhedral loop and data-locality optimizer
     PYCLANG=off: Install python bindings to libclang
     STATIC_LIBS=off: Install static libraries (does not effect sanitizers)
====> Options available for the single BACKENDS: you have to select exactly one of them
     BE_FREEBSD=on: Backends for FreeBSD architectures
     BE_NATIVE=off: Backend(s) for this architecture (AArch64 ARM)
     BE_STANDARD=off: All non-experimental backends

rust does not currently build on my system so I can not build the ports llvm17 or llvm-devel.
