    _______________________________________________________

Details:

On some systems, the installation of h5cc is such that `h5cc -show` produces
more than one line. 
This breaks the macro and produces an invalid Makefile. 

This proposed change just calls `head` before the call to `awk` to make sure
only the first line (the relevant one) is used.
