Bug 210551.
Fix compilation on mips
Original commit message by Christopher Martin, debian bug 342545.
* Add a patch, courtesy of Steve Langasek, that fixes
qt-x11-free's longstanding intermittent FTBFS on hppa, caused
by "the bogus assumption in src/tools/qlocale.cpp that a
char[] can be cast to a double *." (Closes: #342545)
