There shouldn't be.  POSIX specifies:

       The realpath() function shall derive, from the pathname pointed to by
       file_name, an absolute pathname that names the same file, whose
       resolution does not involve '.' , '..'  , or symbolic links.
                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^

Re-build, of course not.  Copy a *BSD libc implementation, perhaps :-)
