It basically means that your git tree is modified.

top-level Makefile calls scripts/setlocalversion, which says (in part):

	# Check for git and a git repo.
	if test -d .git && head=`git rev-parse --verify --short HEAD 2>/dev/null`; then

		# If we are at a tagged commit (like "v2.6.30-rc6"), we ignore
		# it, because this version is defined in the top level Makefile.
		if [ -z "`git describe --exact-match 2>/dev/null`" ]; then

			# If only the short version is requested, don't bother
			# running further git commands
			if $short; then
				echo "+"
				return
			fi
