 # error "You must build your code with position independent code if Qt was built with -reduce-relocations. "\
    ^

This looks straightforward enough. As it says in its message, the Qt #error check looks like this:

#if !defined(QT_BOOTSTRAPPED) && defined(QT_REDUCE_RELOCATIONS) && defined(__ELF__) && \
    (!defined(__PIC__) || (defined(__PIE__) && defined(Q_CC_GNU) && Q_CC_GNU >= 500))
# error "You must build your code with position independent code if Qt was built with -reduce-relocations. "\
         "Compile your code with -fPIC (-fPIE is not enough)."
#endif

And pay-service's CXX_FLAGS look like this:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -g -fPIE ${GCOV_FLAGS}")

This bug was fixed in the package pay-service - 2.0.0+15.10.20150730-0ubuntu1

---------------
pay-service (2.0.0+15.10.20150730-0ubuntu1) wily; urgency=medium

  [ Charles Kerr ]
  * Build pay-service with -fPIC instead of -fPIE because Qt+gcc5 needs
    it. (LP: #1479526, #1478711)
