Remove .eh_frame zero terminators
The machinery to do this was there, but not enabled if the terminator
was the only thing in the section.
bfd/
* elf-eh-frame.c (_bfd_elf_parse_eh_frame): Don't exit early
for a section containing just a terminator. Allow multiple
terminators at end of section.
* elflink.c (bfd_elf_discard_info): Iterate over .eh_frame
sections when not adding alignment. Assert on terminator in
the middle of FDEs.
ld/
* testsuite/ld-elf/eh3.d: Update.
* testsuite/ld-elf/eh4.d: Update.
