The recipe builds the framework for kernel-selftest. Now, it just
contains two sets of testcase, bpf and vm. We are appending others
to the recipe.

It needs some features which will be written into relevant recipe.
But now, you should add them to conf/local.conf manually.
KERNEL_FEATURES_append += "features/bpf/bpf.scc"
