The BBC radio player quirk has been removed in 266597@main (9b58b4bed53b), which is a back-merge of 259548.824@safari-7615-branch (cff01e3). But this commit did not remove the Quirks::staticRadioPlayerURLString() method initially removed, and a second quirk part added in 261190@main (ae690092de53) which is now irrelevant and potentially broken. This also breaks build without ITP support. See also the restricted bug 257352.
