[Buildroot] [PATCH 1/1] xenomai: Add config for enabling SMP for 3.x

[Pawel Sikora <sikor6@gmail.com>]

Add a config option for enabling SMP in Xenomai
userspace, only for versions >= 3.x

In 2.x versions this option was enabled by
default, so for now behaviour for it will
not change, while as buildroot supports
now Xenomai 3.0.3 it's good to let users
have this option.

Add a comment about this config's behaviour
above this option in the menuconfig.
