This patch only modifies `flang` - the bash wrapper script.

`-fopenmp` is required to enable the OpenMP extension in the frontend
and to make sure that the required libraries are linked when generating
the final binary. This patch makes sure that `-fopnemp` is used for both
unparsing and the code generation (via the host compiler).
