trace-cmd: new package
This commit adds a new package for the trace-cmd tool. This tool is a command line front end of ftrace. It collects traces on your target. You can analyse these traces on the target or on the host via the gui "kernel shark". [Thomas: use TARGET_CONFIGURE_OPTS, define _GNU_SOURCE to get O_CLOEXEC definition on uClibc, add thread and largefile dependencies.] Signed-off-by: Pierre Floury <pierre.floury@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
