If the feature is off per default, that should be enough to make it a 
"safe" feature.  User will know what options they are activating.

What I don't like is the "--shrink-ivt", I'd rather prefer something 
less cryptic like "--shrink-vectors" or "--optimize-vectors" or similar.

One technical question:

Does this really need binutils changes, or could it be achieved by 
linker script improvements, e.g. start .text after the last .vector?

Currently the size of .vectors is forced by crt.o, but maybe there are 
other way to do it?
