[PATCH][ARM]. Fix a 64-bit portability bug in cortex_a8_erratum_scan.

[Doug Kwan (關振德)]

I did not really cast all constant operands in offset related
expressions.  I think this ChangeLog entry is more accurate.

        * elf32-arm.c (cortex_a8_erratum_scan): Change type of offset
        to bfd_signed_vma.  Cast constant operands which are used in
        offset related expressions to bfd_signed_vma type as appropriate.
