[PATCH] Don't fail when an existing directory can't be created.

["David Kågedal" <davidk@lysator.liu.se>]

This makes it possible to install in a writable directory not owned by
the current user.

I install git in /usr/local/*, to which I have write permission, but
I'm not necessarily the owner of. The permissions may look something
like this:

  drwxrwxr-x 2 root adm 4096 2008-08-07 17:54 /usr/local/bin/

To do this I set prefix=/usr/local and run "make install".
Unfortunately, this fails miserably because the install rules insist
on changing the permissions on any directory it installs to to
755. This of course fails because I'm not the owner. And even if it
worked, I wouldn't want it to do that.

This patch is just a simple fix to make the install not abort when it
fails to modify the directory permissions, but I have to ask why it
tries to do this at all? Most other programs I have built and
installed do not try to do this.
