Stephan, if I am not mistaken (and someone please correct me if I am
wrong), installing Rustc does not install LLVM, at least not in the
system-wide sense. It downloads a precompiled version of LLVM for Rustc to
use. Other packages that rely on LLVM need the system-wide installed LLVM
package as detailed in the LLVM instructions for BLFS.

I'm not sure where the libglvnd dependency would have come from. Based on
the note on the Mesa page of BLFS and what I know of libglvnd, libglvnd is
a translation layer that allows OpenGL drivers provided by various
implementations to coexist (i.e. Mesa drivers and proprietary NVIDIA
drivers).
