See package/perf/ in the current Git version of Buildroot (it isn't part of the latest stable 2012.11 release, but it will be part of 2013.02). See http://git.buildroot.net/buildroot/tree/package/perf. If it somehow doesn't work for you, do not hesitate to report issues, we'll try to fix them. Thanks!
