OpenBSD: redefine g++/gcc commands to eg++/egcc to use newer gcc 4.9

Browse Source 
On OpenBSD, the system compiler shipped is still gcc 4.2.1 but for proper
C++11 support in Qt, QtCreator and Qt-based projects we need to use
the compilers provided in ports/packages which have the binaries renamed
to eg++/egcc. Therefore, redefine the variables from g++-base.conf to
use the newer compilers.
