The mentioned symbols are no longer external, and have been removed in
upstream commits:

https://github.com/WebKit/WebKit/commit/a1c80bec178456c109a62723ff937405cdb35b6b
Since the former does not apply cleanly due to edits in the ChangeLog,
merge the functional changes in a single port patch file.
