dirfd doesn't exist in some platforms.

dirfd doesn't exist in some platforms.

Hack that should get the buildfarm back to green.
Ensure dirfd() needs to be defined before we properly return fdopendir.
This will do until we get a proper dirfd() defined in libreplace.

From http://www.gnu.org/software/hello/manual/gnulib/dirfd.html

This function is missing on some platforms: AIX 7.1, HP-UX 11, OSF/1 5.1, Solaris 10, mingw.
