I wish I'd trusted my instincts here, and not believed your report that
dynamic section syms look OK. They aren't OK at all. .dynsym section
contents are left uninitialised, and you've just been lucky that all
your bfd_alloc's happened to return zeroed memory. I'm seeing this:
10: 00011a38 0 SECTION LOCAL DEFAULT 19
11: 00011a3c 0 SECTION LOCAL DEFAULT 20
12: 00000034 143 FUNC GLOBAL DEFAULT UND
Please fix.
