I found that the previous fix patch of mine was insufficient for
fixing the problem relevant to EL32. It was necessary that one should
use the 32-bit datatype for section headers instead of the 64-bit one.
Here is a patch complementing it.

I made a runtime test for this fix patch, confirming that the
functionality works well.

Thanks,
HATAYAMA Daisuke
