I've just hit this problem too,  and can demo it without QEMU involved

$ cat e.c
#include <stdio.h>
#include <stdlib.h>

  int main(int argc, char **argv) {    fprintf(stderr, "Hello\n");    
exit(EXIT_SUCCESS); }

$ x86_64-w64-mingw32-gcc -pie -o e.exe e.c 

the resulting e.exe fails to run under *both* Wine and Windows 2008r2.

Either there's some extra magic compiler flags we need to pass to make
this work, or we need to just disable PIE on Windows. The original
pre-meson build used -no-pie AFAICT.

Daniel
