curl: work around mysterious xcopy failure

When building with Win32 make, the xcopy at the end of the build fails
with "Invalid arguments" error, which is clearly wrong, since the
arguments are exactly the same as before, and furthermore curl is not
built with GNU make at all, but with nmake!  W-T-F?
