Paul Moore Aug. 16, 2016, 8:11 p.m. UTC 
The top-level Makefile defines _GNU_SOURCE by default which causes the
following build warning:

    cc -g -O0 -Wall -D_GNU_SOURCE userns_child_exec.c -o userns_child_exec
    userns_child_exec.c:11:0: warning: "_GNU_SOURCE" redefined
     #define _GNU_SOURCE

... this patch first checks to see if _GNU_SOURCE is defined before
defining it again.  We're doing it this way, instead of removing it
entirely so that the test will still work outside the testsuite.
