intermittent 0-length for .note.gnu.arm.ident

This sounds like memory corruption of some kind.  I would suggest 
enabling memory debugging if you have that support available, or else 
adding some debugging of your own.

Note - the arm_add_note() function was removed a while ago, so you may 
find that upgrading to newer binutils sources will solve this problem 
for you.
