Ok, I looked now, and it's because the definition of HAVE_BPF_JIT is
inside the "if NET" thing.

So if NET isn't enabled, then HAVE_BPF_JIT doesn't really *exist* as
an option. Doing a "select" on it is thus not a good idea.

I bet you could just move the two lines

  config HAVE_BPF_JIT
          bool

up to the top of net/Kconfig (so that HAVE_BPF_JIT is available
unconditionally), and then remove all the "if NET" from the four
architectures that support it.
