From 18e39913d41ca4d63e9e94a2ad25b5ea31caaa7f Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 4 Oct 2006 02:15:32 -0700 Subject: [PATCH] [PATCH] Fix spurious error on TAGS target when missing defconfig Not all architectures have a file named 'defconfig' (e.g. powerpc). However the make TAGS and make tags targets search such files for tags, causing an error message when they don't exist. This patch addresses the problem by instructing xargs not to run the tags program if there are no matching files.
