Both gdb and lldb offers a way of substituting source paths, so it should be possible to substitute a path from the build box with a local path at the time of debugging. Qt Creator could do this automagically.

(gdb) set pathname-substitutions /buildbot/path /my/path
(lldb) settings set target.source-map /buildbot/path /my/path

I think recent Qt Creator has a simple checkbox to do it for you.
