+Subject: trace-cmd: Change the way of getting python ldflags.
+
+Prior than this patch, Makefile detects python ldflags using a hardcoded
+python command. It will cause problems if we are building against
+python3 in the future when ldflags for python2 and python3 are
+different. With this patch, python ldflags are detected by
+corresponding python{,3}-config which will detect the right config for
+python plugins.
