::rename on RTEMS does not meet several POSIX requirements, despite
compliance with C and C++ standards. ::std::filesystem::rename, in
turn, has requirements borrowed from POSIX, so it would have to be a
lot more than a simple wrapper around ::rename on RTEMS, and even then
fall short.
Until RTEMS reimplements ::rename for POSIX compliance, expect
filesystem rename tests to fail on it.

rtems.
