Yes.  In GCC terms it would be an option -fextension- taking a joined 
argument - but GCC would be documented not to do anything with that 
argument.  So it would be a general escape hatch for people wishing to use 
specs to process options unknown to GCC.

As a general discipline, I'd probably advise people making use of this 
option to use some informal namespace for their -fextension- options, e.g. 
-fextension-sh-bsp-x rather than just -fextension-x.

I don't plan to propose a patch, but you are welcome to do so.  Since it 
would be an extremely simple patch, we could also consider it for 4.7
