:-)  I think you have three options:
a) Issue an error, and refuse to link the bad object file, or
b) Create a new target with elf_bad_symtab set for the target, or
c) Provide some other means of setting elf_bad_symtab.

I really don't like (b).  (c) is a pain, since it isn't just ld, but
objcopy, objdump, etc.
