Is supporting 32-bit binaries with namei hacks and /emul/netbsd32 a good
idea? Wouldn't be better to have /usr/lib and /usr/lib32 (or /usr/lib and
/usr/lib64 or /usr/lib32 and /usr/lib64)?

(Excuse my ignorance, I don't have any 64-bit machine yet.)

IRIX has /usr/lib for O32 ABI, /usr/lib32 for N32 ABI, and /usr/lib64 for
64-bit ABI:
