Where to put different earm binaries?

[John Klos <john%ziaspace.com@localhost>]

Hi,

I'm running a bulk build of pkgsrc-2015Q1 for NetBSD 7 for both earm 
(earmv5) and for earmv6hf. Should they each have their own directory in 
/pub/pkgsrc/packages/NetBSD/?

There's a chance I may run earmv4 on another machine. Would those go in 
arm since earm is v5?

Thanks,
John
