I could not find a good argument to present to upstream to change this
behaviour, except "gcc has been doing it for x years, without a good
reason". :-)  And I did not want to make yet another FreeBSD specific
change.

In my opinion, gcc is losing information here, e.g. the original
pathname to the source file.  There is no reason debugging tools cannot
be fixed to be able to cope with this.
