We already have a few extraneous things like -fobjc-legacy-dispatch that should really not be there as stand-alone options.

Splitting the argument into name and version works for me.  We'd want to separate "mac" into two different "darwin" and "darwin_fragile" runtimes.  For GNU, that distinction is implied by "gcc" (fragile) vs. "gnustep" (non-fragile) vs. "objfw" (currently fragile, but we'll see)?
