Description:

In June 2020, the official kreport repository fixed a bug that caused builds to fail, in 5d3053e[1] commit.

Debian distro also currently applies this commit as a patch.[2]

On Arch Linux x86_64, this commit was not applied, and I'm not sure why this didn't cause any problems.

But when I try to compile kexi package on Arch Linux RISC-V (kreport is a dependency of kexi), I get errors:

```
/usr/bin/ld: /tmp/cclr1HhW.ltrans0.ltrans.o: in function `.LVL2708':
/usr/include/qt/QtCore/qobject.h:524: undefined reference to `KReportGroupTracker::qt_metacast(char const*)'

/usr/include/qt/QtCore/qlogging.h:68: undefined reference to `vtable for KReportGroupTracker'
collect2: error: ld returned 1 exit status
```

I have checked and confirmed that on Arch Linux x86_64, the compiled kreport.so does not contain symbols about `KReportGroupTracker`. I don't know why this doesn't cause a compile error on kexi x86_64, but it does on kexi RISC-V. (If anyone knows why, I'd be happy to get an explanation)

After I applied that patch manually, the compilation worked fine for both x86_64 and RISC-V.

The attached file is a patch for kreport's PKGBUILD.
