since GNU GLOBAL v6.6.5. Update the documentation accordingly.

====================== =============== ========================================
.. [#f1] Sphinx is needed only to build the Kernel documentation
enabled. You will also need openssl development packages to build kernels 4.3
and higher.
+gtags / GNU GLOBAL (optional)
+-----------------------------
+
+The kernel build requires GNU GLOBAL version 6.6.5 or later to generate
+tag files through ``make gtags``. This is due to its use of the gtags
+``-C (--directory)`` flag.
