[PATCH v2 11/15] libtracefs: Have sample build look cleaner

[Steven Rostedt <rostedt@xxxxxxxxxxx>]

From: "Steven Rostedt (VMware)" <rostedt@xxxxxxxxxxx>

The build of the samples directory just showed the raw commands. This is
inconsistent with the rest of the build system. Make it cleaner by showing
EXTRACT, COMPILE SAMPLE OBJ and COMPILE SAMPLE for the samples being
extracted and built.
