This is in contrast with i386-linux-gnu, where the definition is 80386+ and actual binaries from distros and others tend to require something more modern like 486+ or 586+. (In other words, for the sake of setting filesystem paths there is no need to be strict about the instruction set.) As long as all the distros are using ARMv7+ anyway, I don't think this will come up much, so I don't mind. The question to ask is: if someone builds an ARMv6+ library using the hard-float ABI, where should they place it on the filesystem? Thanks for explaining.
