Bug#1003395: plfit FTBFS on s390x

[Heinrich Schuchardt]

Control: tags -1 + patch

As already indicated in https://github.com/ntamas/plfit/issues/38 the 
problem is related to the size of long double.

The appended debdiff solved the problem on Ubuntu Jammy by forcing long 
double to 64bit.

Best regards

Heinrich
