MXE and Qt 5.9.0

[Dirk Hohndel]

5.7 didn't appear to include the esri plugin... That's why I tried to switch to 5.9. And because of the way mxe is organized, that brought with it the switch from GCC 4.x to 5.4 which is what I suspect might be the cause of my problem...

to my understanding Qt Location with Qt Positioning was available
since Qt 5.0 (https://wiki.qt.io/New_Features_in_Qt_5.0#Add-ons).
my statement "you need Qt 5.9" should not be taken literally. it's
more in the lines "this was developed with 5.9 and i haven't tested it
with earlier Qt versions".
