trace-cmd: fix largefile build problem
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: http://autobuild.buildroot.net/results/1c4567a230940a5287d03e2a5c2c7afbdc64cd36/build-end.log Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
