I'm not sure I follow this one.

The sysroot, by defining the top-level of the debug-info tree, provides 
a consistent root for locating both:
  -> the debug info
  -> the source code
directory search paths are different, so, I think, would want to be 
manipulated using a separate command; and their interaction with sysroot 
would need to be carefully considered.  For instance, given $SYSROOT, 
should it search $SYSROOT/$DEBUGPATH?

Yes, definitely.
