Yes, we should consider this situation, I will do the investigation to 
find the fix

OK, with some investigation done, I will try to collect the requirements 
for discussing.

Maybe we should introduce -debug-pprefix-map in reference/development
manual, I will file a doc requirement in bugzilla.

So it's just a start, we should continue to work on:

1) Support to remap ${S} outside of the WORKDIR (shared work dir)

2) Add -fdebug-prefix-map usage in manual
