From f5031fb37ceef83c85f0dfec773da75c05b2a631 Mon Sep 17 00:00:00 2001 From: Markus Lehtonen Date: Fri, 18 Mar 2016 09:41:51 +0200 Subject: externalsrc: use shared stamp directory if B=S We have a common build directory for all target architectures if externalsrc is used and ${B}=${S}. In this case we also need to have a common stamp directory. The reason is that e.g. changing MACHINE will basically "invalidate" the artefacts in ${B} (wrt. to the new MACHINE) but old stamp files with matching hashes from an earlier build might be available in the machine-specific stamps directory and tasks would not be correctly re-run. Previous attempt in f44f12af346888bdeb3ae01a275cb5dd4396b505 to handle this correctly was faulty as it threw some spurious warnings and caused do_configure to be re-run in every build if that would not be necessary.
