Let me rephrase my question

  1) Is there any automated way to have the compiler pick the debug
     library when a program is linked with -g?
   
  2) Does the compiler skip the debug version if -g is not given?

  3) Not everyone can install under /usr/lib/debug nor even desirable
     in all circumstance.

My questions aren't criticisms.
