I think I'm not making myself clear :).

It doesn't matter whether there's a way to grab something from the OS
and put it into a make variable without stripping the newlines.

Why not?

Because even if you _have_ a variable with contents that contains
newlines, you can't _USE_ it for anything.  You can prove that to
yourself by making an internal variable with newlines using define, and
then trying to use it:

  define CONFIG_SPEC
  element * CHECKEDOUT
  element * /main/LATEST
  enddef

Now this variable $(CONFIG_SPEC) contains a real newline character.

So, that's why we're asking what you're trying to use the value for;
that is where you have to redesign your approach, not where you try to
read the value in.

Have fun!
