Agreed

I don't agree with this, because you need to change a whole set of flags
depending on which runtime you are using. -L-l is just not good enough.

This will fix the debug vs. normal runtime, true, but it doesn't help to
*easily* use a different runtime library, you have to mess with the config
file, but I want a way to do it from the command line, so it can be integrated
in the build system.
