Use flag added: kernel_perf.
Set, to enable building the perf utility. May there after be used in e.g.
rootfs by adding util/perf to the list of RDEPENDS

Hi Christian

Could you create a recipe for building perf (and possibly other
user-space commands) from kernel sources in a seperate recipe instead?

Where as kernel recipe will often be machine specific, it would often
not make sense to have fx. the perf utility built as machine specific,
and thus potentially causing an otherwise common rootfs to become
machine specific.
