Here is a condition needed. This is only valid for some C/C++ recipes.
But now these extensions are also installed e.g. for Rust, Go, Python
which is wrong.

Same issue as above: There are many recipes were a C/C++ compiler
configuration is wrong. As a next step we might add e.g.
  elif autotools
    ...
  else
    return
but we cannot add a general else statement here.
