From aebb0a729f583fd8d1adf321ee3cea4050c21997 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Wed, 2 Aug 2017 00:52:13 +0200 Subject: [PATCH] package/skeleton-custom: rework the merged_usr and building conditions skeleton-custom.mk contains a huge condition for BR_BUILDING and for BR2_ROOTFS_MERGED_USR. This makes the code difficult to follow, so rework the condition a bit so that only the parts that really need to be conditional are indeed conditional. Note that there is no overhead in needlessly evaluation the "stat" commands. Indeed, the assignments use late evaluation so the "stat" is only executed when evaluating the condition - when skeleton-custom is not selected, stat is never called. Signed-off-by: "Yann E.
