Currently, when `mips_elf_calculate_relocation' is asked to relocate an
undefined symbol, it reports an error or a warning and immediately
returns without performing the relocation. This is fine if the link
fails, but if unresolved_syms_in_objects == RM_GENERATE_WARNING, the
link will continue and output some unrelocated code, which is a
regression from commit e7e2196da3 ("MIPS/BFD: Correctly report
undefined relocations").
Fix this by continuing after calling the `undefined_symbol' hook unless
this is an error condition.

* elfxx-mips.c (mips_elf_calculate_relocation): Only return
after calling `undefined_symbol' hook if this is an error
condition. Assume the value of 0 for the symbol requested
otherwise.
