Honour the spirit rather than the implementation of the previous changes;

if we are invoked with -m, use chmod() on the final directory component
in order to ensure the mode is correctly set.

Make this compile, and honour the spirit of the original design while

putative style bugs introduced.  Others doubtless remain.

- mkdir -m should call chmod because the high-order bits get ignored

Fix several problems with mkdir:

1997-04-01T23:46:22+00:00

1)  Fix mkdir -p to exit with the proper exit status and issue an error
    message if it was unable to create all of the specified directories
    and they did not previously exist.  POSIX says:

    The mkdir utility shall exit with one of the following values:

    0  All the specified directories were created successfully or the
       -p option was specified and all the specified directories now
       exist.

    E.g.

    % mkdir -p /var/mkdir
    mkdir: /var/mkdir: Permission denied

    % touch /tmp/file
    % mkdir -p /tmp/file/dir
    mkdir: /tmp/file: Not a directory

    Previously the above examples would exit with a zero exit status
    and no error message.  Something like the following run as a
    normal user will still not produce an error:

    % id
    uid=629(mpp) gid=629(mpp)....
    % mkdir -p /usr/local/etc
    % ls -ld /usr/local/etc
    drwxr-xr-x  4 bin  bin  512 Dec 26 14:55 /usr/local/etc/

2)  Cleaned up the mode handling to be more efficient when multiple
    directories are being created.

3) Fixed a problem where directories could be created with the wrong mode
   if the the -p option was specified and the build() routine returned
   and error.  It would leave the umask set incorrectly at this point.

4) Removed an unused variable.

Closes PR# 2304.
