Fedora development has recently adopted gcc5, and we've run into several 
problems, one of which is that qt-4.8.6 fails to build, when linking 

.obj/release-shared/qdrawhelper_sse2.o: In function `unsigned int const* 
qt_fetch_radial_gradient_template<QRadialFetchSimd<QSimdSse2> >(unsigned 
int*, Operator const*, QSpanData const*, int, int, int)':
undefined reference to `qt_memfill32'
collect2: error: ld returned 1 exit status

same problem with latest 4.8.7 2015-02-02-3 snapshot.

Currently tracking issue @

anyone with similar or different experiences?
