arm-netbsd appears unmaintained.  Apart from the desirability of moving 
NetBSD to EABI, there's a clear bogosity in arm/netbsd.h I noticed a while 
back:

/* Although not normally relevant (since by default, all aggregates
   are returned in memory) compiling some parts of libc requires
   non-APCS style struct returns.  */
#undef TARGET_RETURN_IN_MEMORY

That's a target hook, not a macro.  The #define is in arm.c; the #undef 
has no effect.  Presumably a broken conversion from macros to hooks, not 
noticed for lack of anyone using recent GCC for this target.
