gnu.cfg: Add xfree() (#2051)
It is hard to find good references, one that describes it a bit can
be found here:
https://manpages.ubuntu.com/manpages/bionic/man3/xmalloc.3pub.html

xfree() can be used instead of free().
A check, to verify that a memory leak is found if the memory allocated
via xmalloc() is not freed, has also been added.
