This and other affected packages provides native and cross compiled package. 

The log file shows that debug symbols for native packages are extracted first
with:

 /usr/lib/rpm/find-debuginfo.sh -j8 --build-id-seed 4.8.6-lp150.43.2
--unique-debug-suffix -4.8.6-lp150.43.2.x86_64 --unique-debug-src-base
mingw32-qt4-4.8.6-lp150.43.2.x86_64 --run-dwz --dwz-low-mem-die-limit 10000000
--dwz-max-die-limit 50000000 -S debugsourcefiles.list
/home/abuild/rpmbuild/BUILD/qt-everywhere-opensource-src-4.8.6

and then the symbols from cross compiled packages with: 

 /usr/lib/rpm/mingw32-find-debuginfo.sh /home/abuild/rpmbuild/BUILD 1

which fails to add the mentioned files to the mingwXX-debugsources.list
