Gnulib fts will not select any other fts implementation.  Look at m4/fts.m4,
which admits that even glibc's version is too feature-poor to use, so
the gnulib fts is always compiled in.  That may change someday in
the future, if glibc ever imports the gnulib improvements, but for now,
you are safe in using the API change of gnulib without any chance
of conflict with feature-poor native versions.
