[PATCH] kernel32/tests: Test CreateFileMapping with a foreign architecture dll

7 Jan 2018

This was written with project Hangover in mind, we hoped that we can get rid of https://github.com/AndreRH/wine/commit/8935bdf941f5f2866c2fa4695eb15d94337fa...
Sadly this seems not to be the case, as Wine already behaves like modern Windows here
