When library is built as single thread and trace is enabled, the test applications in test folder fail to compile. In the file aoclos.c the function AOCL_gettid() uses "omp_get_thread_num() to get thread_id, which is only enabled when OpenMP based parallel BLIS library is generated. To fix this in single thread case we now return zero for thread id, openmp function is used only when BLIS_ENABLE_OPENMP macro is defined. However this is not a complete fix. If library is built with pthread, AOCL_gettid() always return 0, which is not the intended behaviour. Change-Id: I5b79ed57d27d0022d3dcab0e2a3a557c8e4ff8ee
