I don't see an need for this. In all the time that GCC's had this
behaviour, I've never heard a request to be able to control this value
for debugging GCC; it's mostly so that people can build the same
sources and get the same .o files.
I don't want to needlessly expand the -v output. It's already pretty big.
You *do* get the value when you use -dA, in the output .s file. I'm
not sure about the benefit of that; it might just be needlessly
preventing people from comparing .s files.

It doesn't seem like a parameter. It doesn't actually change GCC's
behaviour, other than a few 6-character strings in the output.
