[KDE/Mac] OSX/CI: qtcurve fails to build on branch master

[Marko Käning]

Hi René and Yichao,

qtcurve currently fails here on my OSX/CI system:
---
Building CXX object lib/utils/CMakeFiles/qtcurve-utils.dir/x11helpers.cpp.o
/Users/marko/WC/KDECI-builds/kf5-qt5/qtcurve/lib/utils/timer.cpp:27:8: error: thread-local storage is unsupported for the current target
static thread_local std::vector<uint64_t> qtc_tics;
       ^
1 error generated.
make[2]: *** [lib/utils/CMakeFiles/qtcurve-utils.dir/timer.cpp.o] Error 1
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [lib/utils/CMakeFiles/qtcurve-utils.dir/all] Error 2
---

Any idea how to solve this?

Greets,
Marko
