Compiling vterm: cc: command not found

[Chris Keschnat via <help-guix@gnu.org>]

Hello, after todays ~guix pull~, I cannot compile vterm anymore. I do not
seem to have ~cc~ installed (anymore?). Am I missing a package? I have
~make~, ~cmake~, ~gcc~, and ~gcc-toolchain~ installed and didn't change
anything on that front.


Steps to reproduce (following the "Manual installation" from the docs[1]):

#+begin_src sh

  git clone https://github.com/akermu/emacs-libvterm.git
  cd emacs-libvterm
  mkdir -p build
  cd build
  cmake ..
  make

#+end_src

Results in:

#+begin_src sh
