Bug#1003395: plfit FTBFS on s390x

close 1003395 0.9.5+ds-1
thanks

Hello.

This was fixed upstream and there is apparently no need to apply
any patch anymore.

I've written the long explanation in the github issue:

https://github.com/ntamas/plfit/issues/38

TLDR: It was fixed by the line in src/CMakeLists.txt saying this:

target_link_libraries(plfit ${MATH_LIBRARY})

Cc:ing all relevant parties.

Thanks.
