I retract this patch, since I have found a better solution to the problem this was going to solve. Passing "-U__LIBGCC_EH_FRAME_SECTION_NAME__" when building crtstuff.c objects completely removes references to .eh_frame. The original patch still resulted in the .eh_frame section being created, since code to add a 4byte NULL sentinel to the end of the section was retained. If someone thinks the original patch might still be useful, I can go ahead and commit it anyway.
