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?
