Sorry for being indistinct!
My intention was to put "AR=gcc-ar NM=nm OBJCOPY=objcopy
RANLIB=gcc-ranlib WINDRES=windres STRIP=strip" in front of "./configure"
(see the '\' after STRIP=strip) instead of copying binaries:

Hi,
I wrote those instructions as I obviously could not find a better way to get Qemu to cross-compile using MSYS2 in Windows.
When you look at configure, you see that only adding the cross-prefix will not find the MSYS equivalents of some tools:
ar="${AR-${cross_prefix}ar}"
looks for x86_64-w64-mingw32-ar.exe and not (as it is named in MSYS2) x86_64-w64-mingw32-gcc-ar.exe
Perhaps it would be better to fix configure for the MSYS2 case so the flags or the renaming are not required?
Best,
Howard
