I do agree with the feature request, but I'm not sure about the implementation. 
It doesn't seem to work well with the cross-compiling support in the driver as 
clearly shown by the amount of tests that need patching. Is cross-compiling a 
concern for you at all? Otherwise I would suggest going a slightly different 
route and use default values iff no "-target" or "target-command" mechanism is 
active. Might need a way to temporarily disable unused flag warnings, but that 
way would be pretty much toolchain independent?
