+None have been defined yet, so reject anybody setting any. Mesa sets
+it to 0 anyway.

+Subject: scripts/tags.sh: Resolve gtags empty index generation
+
+From: Ahmed S. Darwish <darwi@linutronix.de>
+
+commit e1b37563caffc410bb4b55f153ccb14dede66815 upstream.
+
+gtags considers any file outside of its current working directory
+"outside the source tree" and refuses to index it. For O= kernel builds,
+or when "make" is invoked from a directory other then the kernel source
+tree, gtags ignores the entire kernel source and generates an empty
+index.
+
+Force-set gtags current working directory to the kernel source tree.
+
+Due to commit 9da0763bdd82 ("kbuild: Use relative path when building in
+a subdir of the source tree"), if the kernel build is done in a
+sub-directory of the kernel source tree, the kernel Makefile will set
+the kernel's $srctree to ".." for shorter compile-time and run-time
+warnings. Consequently, the list of files to be indexed will be in the
+"../*" form, rendering all such paths invalid once gtags switches to the
+kernel source tree as its current working directory.
+
+If gtags indexing is requested and the build directory is not the kernel
+source tree, index all files in absolute-path form.
+
+Note, indexing in absolute-path form will not affect the generated
+index, as paths in gtags indices are always relative to the gtags "root
+directory" anyway (as evidenced by "gtags --dump").
