Preloader Make untar failing.

In my case, the file "tar.exe" was in the folder "c:\window\system32". I ran "make -j -d" and at the end saw, that "make" would try to start "c:\windows\system32\tar.exe zxf ..." instead of cygwin path. Of course, windows tar can't to recognise unix path and finishes with error "File not found". So, I deleted "tar.exe" in "c:\window\system32" folder and this is a solution for this issue.
