functions.sh: TOPDIR was being expanded in the cat statement leading to build errors like this:

11:00:18 ERROR: Execution of event handler 'check_sanity_eventhandler' failed
11:00:19 ERROR:  OE-core's config sanity checker detected a potential misconfiguration.
11:00:19     Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
11:00:19     Following is the list of potential problems / advisories:
11:00:19
11:00:19     BBPATH references the current directory, either through an empty entry, or a '.'.
11:00:19 	 This is unsafe and means your layer configuration is adding empty elements to BBPATH.
11:00:19 	 Please check your layer.conf files and other BBPATH settings to remove the current working directory references.
