Thanks.

I tried that, but unfortunately I think it didn't really work -- gnulib
still builds and uses _gl_convert_FILETIME_to_POSIX and
_gl_fstat_by_handle.

I considered two other approaches:

1. Link BFD and binutils against gnulib.  This seems like a pain because
   at least Fedora installs libbfd.so, so we'd either have to arrange to
   build a gnulib.so (I guess under some other name) or get the gnulib
   objects into the shared libbfd... ugh.

2. Use --avoid=stat --avoid=fstat.  So far this seems like the best
   approach.  Pedro pointed out that this means we won't get any gnulib
   fixes for other bugs in this area.  However, given gdb's relatively
   minimal needs from stat, and given the fact that gnulib is
   introducing other bugs, this seems like an acceptable tradeoff to me.
