With the attached testcase on mips64-elf toolchain when disassambling a o32
application which crosses addresses from 0x7fffffff to 0x80000000 objdump goes
haywire and keep on disassmbling symbol at 0x8000000.
Debugging it a bit I figured that the symbol values which are unsigned long long
are read in as signed long long at bfd_elf32_swap_symbol_in() function because
sign_extend_vma is set for mips in bfd. All the address calculations in objdump
are done unsigned for addresses and when it encounters a symbol with value
0x80000000 bfd sign extends it before putting this value into the asymbol
structure and it becomes 0xffffffff80000000 which is a large unsigned number and
all adress comparsions which involve the sybmol value start to fail.
