Bug#870204: RFS: openfst/1.6.3-1 -- weighted finite-state transducers library

[Giulio Paci]

Dear mentors,
        as Jakub, my former sponsor for this package, is not available, I am 
looking for a new sponsor.

Please note that this package also closes #871170 (FTBFS with gcc-7).

Thank you for your help.

Best regards,
Giulio
