#     selftests/powerpc: Fix compile error on tlbie_test due to newer gcc
#     
#     Newer versions of GCC (>= 9) demand that the size of the string to be
#     copied must be explicitly smaller than the size of the destination.
#     Thus, the NULL char has to be taken into account on strncpy.
#     
#     This will avoid the following compiling error:
#     
#       tlbie_test.c: In function 'main':
#       tlbie_test.c:639:4: error: 'strncpy' specified bound 100 equals destination size
#           strncpy(logdir, optarg, LOGDIR_NAME_SIZE);
