You mean the default is not something sensible and you get byte at a
time output if this option isn't set?  If so, then we should add this to
std.armv6.

Personally, I rather prefer the byte at a time output, because when
crashes and other bad things happen, there are clues in the way the
output is interleaved.  I can see how it isn't exactly user-friendly
though. :)
