Thanks, but we already have a perf package. 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!

Thomas
