Unfortunately, this seems to have broken Rust, and thus IceCat.  See:

  https://hydra.gnu.org/build/3179552

I don't have time to look at this right now, but please also keep in
mind the following commit:

  commit f8cba3ff4fc6aed0c539700aa47b6e8f4c25c34d
  Author: Marius Bakke <address@hidden>
  Date:   Sat Nov 17 22:54:03 2018 +0100
  
      gnu: mesa: Stay on RTTI-less LLVM.
      
      * gnu/packages/llvm.scm (llvm-without-rtti): New public variable.
      * gnu/packages/gl.scm (mesa)[inputs]: Use that instead of LLVM.

I would suggest simply reverting both of these commits for now, and
building this change out on another branch, possibly 'core-updates'.

IceCat should not be left broken longer than necessary.

     Thanks,
       Mark
