The Portable Paranoid's version is to use e.g. "cp foo /usr/local/"
That will complain if not existing, and use /usr/local// otherwise.
But one can't get carried away and use that workaround everywhere...

directories are created first, which also helps when using DESTDIR:
mkdir -p /usr/local
cp foo /usr/local
