Another update to the mga_xorg7_installer

Today I read a topic in the Matrox General Linux Forum where a user had problems to run this script on his machine.

The reason for this was the abscense of an installed C++ compiler, so I have to check for this too in the script.

ChangeLog:

1.1.1 Added missing dependency to g++
      * g++ is also needed to compile this driver
