  Okay, so it's a 64-bit ABI that is called n32 by accident :-)

  Since it's not clear if lib32 is needed for other architectures, and 
since we don't always do it for the 64-bit architectures, it's probably 
better to keep your original condition on $(BR2_MIPS_NABI32).

  Probably it's best if your patch goes in as is, and it can be 
refactored later.

  By the way, shouldn't the same be done in STAGING_DIR?
