From 2a97045d5daeb7cb7222f1ffe0532930d5b3140d Mon Sep 17 00:00:00 2001 From: Thomas De Schampheleire Date: Thu, 21 Jun 2012 19:34:50 +0000 Subject: build: add option to exclude executables/dirs from being stripped Sometimes it may be desirable to keep debug symbols for some binaries and libraries on the target. This commit introduces the config option BR2_STRIP_EXCLUDE_FILES, which is interpreted as a list of such binaries and libraries, and the option BR2_STRIP_EXCLUDE_DIRS, which indicates directories excluded from stripping entirely. These exclusions are passed to the find command in the target-finalize step.
