the inputs need to be deduped based on basename and the order specified. so
i'd build a hashmap/associative array from the basename to the full path, and
then output the resulting set.
this isn't something sort/uniq can accomplish.
it is possible to do in awk, i've just been a bit shy about using it as i'm
not confident in portability aspects (beyond POSIX). if we agree POSIX is
fine (which, for newlib, i think is OK), then yes, we can do that.
