[PATCH] Fix build of gold/mips.cc with GCC 4.3

[Richard Biener]

I need the following to fix build with GCC 4.3 which with -m32 complains
about 0x800080008000 being too large for 'long' type.  GCC 4.8
doesn't complain so not sure whether it just silently discards extra
precision or if the standard mandates a long-long literal here.

Richard.
