2012-10-18scripts/cp-noerror: Try and use hardlinks if possibleRichard Purdie1
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.

2012-05-30scripts/cp-noerror: Add a special copy function to fix autotools issuesRichard Purdie1
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.
