Use --program-transform-name / --program-suffix.  Directory names already
contain the gcc version.

Maybe I was too short with the description. Same version, something else 
different should also work, so there need to be different directory 
names. That is, the two gcc's should not share *anything*. This means 
you'd also need to set some lib paths.

The effect should be similar to a different --prefix, except done not by 
changing the top level but lower.

I believe I've seen tips to do this seen at least twice in the recent 
past, so it seems to me it would be good to be able to do it with one 
option instead of having to know to combine three or so.

That's been broken for some time on x86_64, see bug 32415

If it's just about the version, perhaps you can make -V working again.
Requires a working --enable-version-specific-runtime-libs of course. :)

Oh same version.  Change the above to "make -b working again".
