[Halld-offline] scons build problem with new split halld_sim

[Paul Eugenio]

I am building an executable from a git branch of halld_sim.   It seems that scons has lost the dependency build.  After modifying a source file, scons will build an updated object file but does not update the executable unless one removes both old executables in the associated $BMS_OSNAME/bin  and  ./$BMS_OSNAME/bin  directories.

See the list of commands and the build times below. I build genr8, then modify the source and rebuild. The object file genr8.o gets updated but the executable does not.  But when I remove the development and the install genr8 executables, scons builds the update executable.

I’m guessing scons has some $HALLD_HOME issues.
