make install on existing emacs fails

[dhruva <dhruvakm@gmail.com>]

Hi,
 I am building CVS HEAD Emacs on WXP using MinGW. The "make install"
fails to install emacs on an existing installed folder.

------------ build o/p ------------
cp -f *.el "e:/GNU/emacs/lisp"
for %%f in (calc calendar emacs-lisp emulation erc eshell gnus
international language mail mh-e net play progmodes term textmodes url
obsolete) do mkdir "e:/GNU/emacs/lisp/%%f"

The following patch fixes this issue:
