Its possible something can delete $1 (since it may be empty) whilst cp-noerror
is starting. Add an exception to handle this issue since if this happens, we
shouldn't return an error.

Since we generally have lots of copies of the directories created using this tool, use
hardlinks where possible. This should save a little disk space and improve performance
slightly.

Currently we copy the aclocal directory to the build so that autotools
doesn't see .m4 files disappear when its processing them. This can happen
if for example, package X is being rebuilt at the same time as Y and it
gets uninstalled from sstate (assuming there are no dependencies between
X and Y). This code making the copy was added to avoid races but introduces
a race of its own, namely that the files can disappear during the copy.
This patch adds a cp-noerror script which silently ignores such errors
and gives the behaviour we need in this case. It hence fixes issues which
crop up for users and the autobuilder occasionally.
