I don't believe that menuselect will enable something for which 
dependency checking resulted in a failure.

Alok: res_timing_timerfd needs a kernel of 2.6.25 or greater *and* glibc 
2.8 or later. Earlier versions of glibc, and probably nearly all other C 
libraries, don't have the API calls required for timerfd to be usable 
from Asterisk. If your cross-compile environment has the proper Linux 
kernel headers and an appropriate version of glibc, then the dependency 
checking for res_timing_timerfd should succeed and it will be enabled.
