* perf: new packageThomas Petazzoni2013-01-072-0/+61
This patch adds a new package that allows to build the 'perf' userspace tool that comes in the tools/perf directory of the kernel sources. It is an alternative proposal to the one done by Kaiwan Billimoria <kaiwan.billimoria@gmail.com>, in that it creates the package in package/perf/. It therefore properly integrates with the Buildroot package infrastructure. Of course, the package depends on the Linux kernel to be built by Buildroot, in order to get Perf sources matching the version of the kernel that will be executed.
