Hold the presses!  Could the fact that the libc being used does not have
a '.symtab' section be the cause of the problem?  For some reason, the
library I was using has a '.dynsym' section, but no '.symtab' section.
I suspect that someone was trying to save some disc space and caused
several problems.

The routine 'bfd_get_synthetic_symtab' takes both static and dynamic
symbol tables as input.  So it's no wonder it's not doing the right
thing if one is missing.
