gold patch: Add casts to avoid warning

[Ian Lance Taylor]

I had to add a couple of casts to avoid a warning about comparing
signed and unsigned values with g++ 4.2.2.  Figuring out the right
casts was a little tricky since this is a comparison between off_t and
size_t, overflow is definitely possible, and it's hard to know which
of off_t and size_t is larger for any given compiler/OS.  I punted and
cast both values to unsigned long long.
