+Relative paths don't work with -fdebug-prefix-map and friends. This
+can lead to paths which the user wanted to be remapped being missed.
+Setting -fdebug-prefix-map to work with a relative path isn't practical
+either.
+
+Instead, call gcc's realpath function on the incomming path name before
+comparing it with the remapping. This means other issues like symlinks
+are also accounted for and leads to a more consistent remapping experience.
