The debugging information (profiling, etc) are always using host's
file-names. So if you create a cross-compiler, the
file-name/path-information stored are always that one of the
host-system. Not of the target.
There is a need of having here some additional mapping features, but
this is for now not addressed by this patch.

For example, use a cross-compiler for windows-native on an unix-OS and
build an application with profiling and/or debugging. Then try to
debug/profile this app on a native windows host. You will notice that
filenames/paths are that one from the unix-OS and therefore are pretty
unusable on native Windows. (The other way around is of course the
same).
