From 7c0fd561bad0250a00cef63e3d787573112a59cf Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Wed, 21 Jan 2015 11:34:50 +0000 Subject: lib/oe/package: Ensure strip breaks hardlinks Normally, strip preserves hardlinks which in the case of the way our hardlink rather than copy functionality works, is a disadvantage and leads to non-deterministic builds. This adds a move into place after the strip operation to ensure hardlinks are broken and we bring back build determinism.
