commit 0276651ab74a1200d8c1defeee3b2a4f53712fe7

[libstdc++-v3] [rtems] enable filesystem support
mkdir, chdir and chmod functions are defined in librtemscpu, that
doesn't get linked in during libstdc++-v3 configure, but applications
use -qrtems for linking, which brings those symbols in, so it makes
sense to mark them as available so that the C++ filesystem APIs are
enabled.
for libstdc++-v3/ChangeLog
* configure.ac [*-*-rtems*]: Set chdir, chmod and mkdir as
available.
* configure: Rebuilt.
