In general I like this idea and I would like somebody to approve it (I
don't approve many binutils patches these days outside of gold).

However, I don't see why this will do the right thing when used with -EB
or -EL, and it seems to me that this matters.  Your patch prints
default_target, but as far as I can see -EB/-EL only affect
output_target.  I think this does need to be tested to ensure that
-EL/-EB work correctly.
