I had some old patches for gcc-ar, gcc-nm etc. That's similar how
other compilers do it.
With that it doesn't matter how long the option is.
The original feedback was that shell wrapper were not portable enough.
I actually did C based wrappers recently, but haven't submitted them
I think wrappers are preferable over shorter options because they
are easier to use and easier to fit into existing makefiles.
The best long term direction probably would be to put a reference
to the plugin into the object files and let BFD find it itself. This
would be most compatible with existing Makefiles. But that would need
