mga_hal broken with X.org 6.9.0

[Peter Jeremy]

The (binary) mga_hal driver in ports/x11-servers/mga_hal only supports
X.org 6.8.1 and earlier.  With the recent upgrade to X.org 6.9.0, any
attempt to install the mga_hal port causes to fail to start (looping
indefinitely).

Unfortunately, there doesn't appear to be an mga_hal driver for X.org
6.9.0 on the Matrox site.  Since it isn't practical to upgrade the
port and there isn't an X.org 6.8.x port available, could it please be
marked "broken" to prevent further confusion.
