title: Cannot generate ORC metadata for CONFIG_UNWINDER_ORC=y
body: <p>I’m big enthusiast of Manjaro since 2015 but today I got a problem that I couldn’t resolve on my own. After big updates done few days ago (by update manager) I have a problem with compiling Kernel Drivers on kernel 4.15.18-1. After call make I got error:</p>
  
  <pre><code>make -C /usr/lib/modules/4.15.18-1-MANJARO/build M=/run/media/mati/common/hello_world modules
  make[1]: Wejście do katalogu '/usr/lib/modules/4.15.18-1-MANJARO/build'
  **Makefile:974: *** "Cannot generate ORC metadata for CONFIG_UNWINDER_ORC=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel". Stop.**
  make[1]: Opuszczenie katalogu '/usr/lib/modules/4.15.18-1-MANJARO/build'
  make: *** [Makefile:4: all] Błąd 2
  </code></pre>
  
  <p>The problem is that I cannot install mentioned libraries and command: <strong>pacman -Q libelf</strong>
  returns
  <strong>libelf 0.170-1</strong></p>
  
  <p>i have no idea what happend, I tried another kernels (I have few versions installed) but each has problems (e.g. the newest, experimental 4.17 has problem with asm goto of gcc compiler). I started learning Linux Kernel Drivers programming but now I can’t learn because of these compilation problems … anyone can help me ?</p>
  
  <p>(Hope my english is understanable).</p>
  
  <p>Greetings !</p>
