* scripts/cp-noerror: Try and use hardlinks if possibleRichard Purdie2012-10-181-1/+9
| | | | | | | | | | | | 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.

* scripts/cp-noerror: Add a special copy function to fix autotools issuesRichard Purdie2012-05-301-0/+15
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.
