I wrote a small script scraping all .o file names from configure.nat, to
see if there is a corresponding .c file (see below if you need it).  The
only bad one it found is "nat/aarch64-sve-nat/linux-ptrace.o", which should
just be nat/linux-ptrace.o, I think.

Other than that, it did fine the _U/_S files for Hurd (e.g. notify_S.o).  There
is no corresponding .c file for that, I don't know if they are generated or what,
but I don't think your patch changes anything about that.

If you run the script, you'll see it also reports gnu.c... it's a false positive
because it matches "gnu.o" in http://www.gnu.org/licenses :).

Overall this series LGTM, thanks!
