The "cp" command doesn't copy attributes

[Numerio]

If I'm not wrong (but double check that) on linux the cp command and potentially other binutils don't copy xattrs. This is a bit of a problem as BeOS does that. The command (cp) can however copy attrs if a flag is passed.

We have two options

1. Patch binutils (seems too much work for the gain, unless you have a good reason to do so)
2. Define a cp alias (and check for other binutils that might need it) so that the flag to copy attributes is passed.
