perf: new package 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.

perf: disable documentation perf uses asciidoc to generate documentation, but /usr/bin/asciidoc will try to use buildroot's host-python which doesn't have the required unicodedata. Recent kernels always try to build the man pages when installing. To avoid that, define ASCIIDOC as an empty string so the Makefile can't find the executable and skips the documentation generation.

define PERF_BUILD_CMDS
perf: add kernel version checks perf is only available since kernel 2.6.31, so if we can't find tools/perf/Makefile, error out and tell the user about this. perf without libelf can only be built since kernel 3.7, so error out and tell the user about this if he's trying to build perf from a < 3.7 kernel without libelf. Unfortunately, those tests can only be build-time checks as we either need to know the real kernel version (i.e, using LINUX_VERSION would not be correct as it can be a Git commit ID, or Git tag), or have access to the kernel sources themselves. So we can't prevent those invalid situations at the configuration, we can only nicely tell the user at build time.
