I see two options:

1. give the Qftcrhb symbol the same name as Qftcr, which might do the
right thing, but would make it harder to work out whether HarfBuzz is
actually being used.

2. just say "If youʼre going to be modern, be modern: Cairo requires
HarfBuzz" (note that this is the path that Pango is taking).
