For questions like this you probably want the help-make@gnu.org mailing
list FYI.

I think the best solution is to escape the "$" so it's passed to the
shell rather than interpreted by make; using the shell function in
recipes is to be discouraged IMO.

So use:

  all : 
         echo $$(pkg-config --libs glib-2.0)

This of course assumes that all other aspects of this system are set up
correctly: running POSIX operations like this on a Windows system
typically requires a lot of other configuration.
