On aarch64 Features (flags on x86_64) isn't last, so I changed the loop
to keep running until the end of the file. I suppose I could've changed
it to run until it hit a blank line and left the eof-object? for #f.

the change from (architecture architecture) at the end I tossed in at
the last minute. It was more to keep it from erroring on untuned
architectures.
