make qreal double by default on all platforms
On modern ARM CPUs there is no speed difference between
float and double anymore, so let's rather use double for
qreal to avoid rounding and precision issues. Like this
we also get much better compatibility with our desktop
OSes.
This is not binary compatible on ARM, but the old behavior
can be restored by passing -qreal float to configure.
