[RFA] NetBSD, mipsnbsd-tdep.c supply_gregset 32/64

[Michael Snyder]

Similar to yesterday's patch, this one accounts for core files.

2007-12-13  Michael Snyder  <msnyder@specifix.com>

	* mipsnbsd-tdep.c (mipsnbsd_supply_gregset): Convert 32/64 bits, 
	for targets in which mips_abi_size != mips_isa_size.
