Bug#768741: phlipple: FTBFS in jessie: ld: engine.o: undefined reference to symbol 'cos@@GLIBC_2.2.5'

[Miriam Ruiz]

Thanks a lot, I'll have a look at it and commit it.Do you want to be
included in Uploaders, as the patch seems to say? If you do, you're
essentially declaring that you're willing to take care of that
package, essentially :)

Greetings,
Miry
