Subject: [PATCH] fix target directory so that it can compile properly without
 linking in fopenmp change inclusion of omp.h in offload.h and thermo.h to
 openmp.h add include guards to openmp.h stub functions add omp_get_num_teams,
 omp_get_team_num, and omp_is_initial_device functions to stubs to ensure
 compilation
