We don't handle .eh_frame section padding properly:
http://sourceware.org/bugzilla/show_bug.cgi?id=2655
When we pad the current .eh_frame section for the alignment of the
next .eh_frame section, we need to know the padding size. Otherwise,
the last FDE size may be wrong. Currently, we assume that all .eh_frame
sections have the same alignment. It isn't true for x86-64 since
the .eh_frame section in crtend.o from gcc has 4 byte alignment.
Ideally, _bfd_elf_write_section_eh_frame knows the real alignment of
the next .eh_frame section. But this info is hard to come by.
A kludge may be to force 8 byte alignment on .eh_frame for x86-64
when we see a 4 byte alignment.
