[PATCH 2.6.12-rc6-git6] Fix large core dumps with a 32-bit off_t

[Daniel Jacobowitz]

The ELF core dump code has one use of off_t when writing out segments.  Some
of the segments may be passed the 2GB limit of an off_t, even on a 32-bit
system, so it's important to use loff_t instead.  This fixes a corrupted
core dump in the bigcore test in GDB's testsuite.
