[Clas_offline] clas x64 builds

[Johann Goetz]

Hi Professor Eugenio,
I fixed this in the build_system. debug=yes works fine but it might be
better to do:

scons build=debug

This will build everything with the debug flag set and put it into a
directory "build_debug". Then you will not overwrite the build=standard
build you had already done.

The idea here is that you have your path set to the install (prefix/bin)
location ($HOME/local/bin/clas6 say) Then you can do:

> scons build=debug install
> a1c    <-- debug version
> scons build=standard install
> a1c    <-- standard version

because install will place a1c in the same location. And scons is smart
enough to know that all that has to be done is to copy over the
executables (and associated libraries) since they are already built. One
can also do build=opt for the optimization flag to be set.
-Johann.
