But to turn your own question back on you, does it?  Adding -mabi=eabi
at this stage might give the wrong impression.

If we did add -mabi=meabi now, it would be a no-op, i.e. the same as
specifying no -mabi switch at all.  All the other -mabi flags leave some
sort of trace in the object file, but -mabi=meabi wouldn't.  So MEABI is
going to be the odd one out one way or the other.

It would be nice to have some way of identifying MEABI code too.
I just think -mabi=meabi should wait until there is.
