 It is easier to add it to the target-finalize target. Then you can be
sure that the ordering is correct (target-finalize already has all the
needed dependencies). You can also easily use conditions there (it's not
inside a define).

 However, I think it will be more appropriate to implement breakpad as an
additional strip alternative. You probably don't want to combine strip
with breakpad... Currently we have none, strip or sstrip, it should be
relatively easy to add breakpad as an additional option. Note, however,
that the strip code is very old, it doesn't satisfy our coding style so
we'll probably want you to do some cleanup first. Also, it is currently
untested in the autobuilders AFAIK.
