From b287c82bed6673648a69be6c1cf84abe8885a3c4 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Tue, 22 May 2018 09:18:33 +0200 Subject: [PATCH] build: prevent spurious package rebuilds under CONFIG_AUTOREMOVE When CONFIG_AUTOREMOVE is enabled, the build system touches an additional ".autoremove" stamp file in the cleaned build directory. Since the autoremove stamp file is touched after the compile process completed, it ends up being the most recent file of the package build directory, causing the timestamp.pl check of depends.mk to erroneously declare the ".built" and ".prepared" stamp files as stale, triggering a forced clean-build submake process. Fix the problem by using the ".built" stamp file as modification time reference when touching the ".autoremove" stamp file.
