That message actually comes from the linker in response to an error during
final link.  See bfd/elf32-hppa.c:elf32_hppa_relocate_section.  It's
saying a particular relocation couldn't be relocated for some reason.  In
this case, the undefined symbol is the cause of the message (not the other
way around), and since the linker already reported the undefined symbol
it's rather redundant.  I should probably not report "cannot handle.." for
undefined symbols.
