libstdc++: check for openat
rtems6.0 has fdopendir, and fcntl.h defines AT_FDCWD and declares
openat, but there's no openat in libc. Adjust dir-common.h to not
assume ::openat just because of AT_FDCWD.
for libstdc++-v3/ChangeLog
* acinclude.m4 (GLIBCXX_CHECK_FILESYSTEM_DEPS): Check for
openat.
* configure, config.h.in: Rebuilt.
* src/filesystem/dir-common.h (openat): Use ::openat if
_GLIBCXX_HAVE_OPENAT.
* src/filesystem/dir.cc (dir_and_pathname): Use dirfd if
_GLIBCXX_HAVE_OPENAT.
