+Subject: [PATCH 01/25] trace-cmd: Fix the logic behind SWIG_DEFINED in the
+ Makefile
+
+At least on Ubuntu, the $(shell ...) command used in the master Makefile to test
+for the existence of the 'swig' command does not work in the negative case.
+That causes the build to report ugly errors in case 'swig' is not installed on
+the system.
+This one-line patch, fixes the problem by using the POSIX 'comamnd -v {CMD}'
+in $(shell ...) to detect the presence of the swig and restores this way the
+fake report_noswig target.
