# Relocations against undefined symbols would be incorrectly let through

# sense.  The link would fail anyway, but for R_MIPS_GOT_PAGE relocations
# a failure of the following assertion:

# BFD_ASSERT (h->dynindx >= global_got_dynindx);
#
# would additionally be reported in mips_elf_global_got_index(), because
# at this point h->dynindx for the undefined symbol would be set to -1.
# Other kinds of GOT relocations allocate a GOT index for the symbol
# referred and set its h->dynindx in _bfd_mips_elf_check_relocs(), but
# R_MIPS_GOT_PAGE relocations only allocate a GOT page at that point and
# for undefined symbols the page never gets resolved any further.
