optimized compilation of external packages result in FairBase test crashes

[fuhlig1]

Fons:

Using:

compiler=Clang
debug=no
optimize=yes
geant4_download_install_data_automatic=yes
geant4_install_data_from_dir=no
make_install=yes
SIMPATH_INSTALL=/Users/rdm/FairRootExt
build_cpp11=false

I get when running "make test" in the build directory:

master [178] make test
Running tests...

^Cmake: *_* [test] Interrupt: 2

The build of the external packages with debug options don't show this problem.

I ask Fons to run "make Experimental", so that we get the output of the failing test.

The problem is due to problems in TGeant3. If this package is compiled with optimization using newer versions of gfortran (the problem was seen with 4.8 (Linux, Mac) and 4.9 (Mac)) either the code crashes during the initilization stage of Geant3 (Linux) or it will run in an infinite loop and never ends (Mac). The solution for the time being (until the problem is solved in Geant3) is to switch of the build of Geant3 with optimization. This is done automatically for the Linux platform but this was missing for Mac OSX. Fixed this now in our install_geant3.sh script
