$ISA indicates the cpu type (Instruction Set Architecture?), for
dealing with 32-bit and 64-bit machines.
On 32-bit machines it should resolve to the null string, so it's
probably meaningless for you.
If you had a 64-bit x86 (AMD) I think you'd get x86_64. sparc9 is
another.
The idea is for the mixed-mode machines you can have 64-bit mode
authenticators and 32-bit authenticators, depending on how the app is
compiled/executed
I'm not sure if a 64-bit app can use a 32-bit authenticator with a
performance hit or if it just won't work.
