Hi
This patch fixes crash that happens if we build too big linux kernel so
that offsets overflow. There are several bugs in elf64-hppa.c:
1. offset is 64-bit, but 32-bit format "%lx" is used. This causes
parameters mismatch
2. eh may be NULL. If it is NULL, I changed the code to print "unknown".
Someone who understands the code better can change it to print something
more descriptive
3. returning bfd_reloc_notsupported causes abort() in
elf64_hppa_relocate_section. Change it to return bfd_reloc_overflow.
With these changes, ld writese error messages on overflow and doesn't
crash anymore.
