Then, NetBSD/mips64.

I believe LP64 is the right way to go for NetBSD/mips. Here is the
incomplete list of 'what should be changed before ...'

Correction and addtion are welcome.

In a directory 'src/lib/libc/arch/mips';

gen/			necessity and reason	note

__setjmp14.S		yes, pointer arith	FP register save/restore
__sigsetjmp14.S 	yes, pointer arith	FP register save/restore
_setjmp.S		yes, pointer arith	FP register save/restore
byte_swap_2.S		no
byte_swap_4.S		no
fabs.S			yes, FP argument
isinf.S 		yes, FP argument
ldexp.S 		yes, FP argument
