[Buildroot] [PATCH 2/2] efl: disallow on non-MMU systems

[Thomas Petazzoni]

The libeina library uses the madvise() system call, that isn't
available on non-MMU systems. Also, several other components of EFL
use fork(). Therefore, the easiest solution is to simply disallow the
EFL as a whole on non-MMU systems.

Fixes:

Thanks to Ryan Barnett for helping in the investigation!
