The .data is placed at some offset in address space (because IRIX did
the same), The introduction of alignment for 64k page size caused then
the preceeding text segment to get padded to the next 64k border instead
of the 4k padding used before.

From the ld changelog:

2005-06-01  Maciej W. Rozycki  <macro@linux-mips.org>

	* emulparams/elf32btsmip.sh: Unset DATA_ADDR.
	
This removes the weird separate .data for "traditional" (linux-like)
mips. Also, in some cases ld -N may be acceptable as a workaround for
the problem.
