The source files of trace-cmd already define _LARGEFILE64_SOURCE, but
Buildroot passes it again on the build command line through CFLAGS,
which causes a build error. We fix this by filtering out our
definition of _LARGEFILE64_SOURCE from the CFLAGS before passing them
to the trace-cmd Makefile.
Fixes the warning visible at:

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.]
