[PATCH/RFA] Fix libffi on mips-netbsd

libffi makes some bad (IMO :-) assumptions about what preprocessor macros
will be defined and which include files will be available on MIPS.

This patch makes it work on mips-netbsd, but I cannot verify it on
mips-linux or mips-sgi-irix.

That said, with this change, libjava hobbles along on mips-netbsd (I posted
a testsuite run with it enabled earlier today).

So, assuming someone can tell me this looks okay for mips-linux and
mips-sgi-irix, OK for mainline?

	* (mips*-*-netbsd*): Treat it like mips*-*-linux*.
	* configure: Regenerate.
	* include/ Test for FFI_MIPS_N32 rather than
	_MIPS_SIM == _ABIN32.
	* include/ffi_mips.h: If _MIPS_SIM is not defined, set
	FFI_MIPS_N32 or FFI_MIPS_O32 based on the presence of
	__mips_n32.  Error out if __mips_n64 or __mips_o64 are defined.
	* src/mips/ffi.c: Only include <sgidefs.h> if __sgi__ or
	__linux__ are defined.  Test for FFI_MIPS_N32 rather than
	_MIPS_SIM == _MIPS_SIM_NABI32.  Test for FFI_MIPS_O32 rathern
	than _MIPS_SIM == _MIPS_SIM_ABI32.
