Add a notice for gdb debugging in component builds

Browse Source 
Since obj files are loaded lazily, in order to set up breakpoints for a
component build, the program needs to run at least once. Add a notice
regarding this behaviour.

*** promo
Notice that in components builds, the debug files will be loaded lazily. Because of this, the program needs to run at least once before breakpoints can be set. Alternatively, gdb will ask for confirmation as follows:
> Make breakpoint pending on future shared library load? (y or [n])
