Description of problem:
The OpenMPI package installs the module-related file /etc/modulefiles/openmpi-%{_arch}, which contains the non-replaced RPM macro %{_cc_name_suffix} in the definition of the MPI_COMPILER environment variable.

Then, when the OpenMPI is loaded (e.g., 'module load openmpi-x86_64'), the MPI_COMPILER environment variable is not correctly set. It is set to 'openmpi-x86_64%{_cc_name_suffix}', where it should be set to 'openmpi-x86_64'.

Version-Release number of selected component (if applicable):
openmpi-1.3.3-6.fc12

How reproducible:
Always

Steps to Reproduce:
1. Install the OpenMPI package.
2. Load the OpenMPI module (e.g., 'module load openmpi-x86_64')
3. 'echo $MPI_COMPILER' => 'openmpi-x86_64%{_cc_name_suffix}'
  
Actual results:
The RPM macro %{_cc_name_suffix} has not been replaced during the RPM package build process.

Expected results:
'echo $MPI_COMPILER' => 'openmpi-x86_64'

Additional info:
Simply adding a '?' (question mark) should do the trick, i.e., replacing 'openmpi-x86_64%{_cc_name_suffix}' by 'openmpi-x86_64%{?_cc_name_suffix}'
I've had a look at the openmpi.spec, and all seems fine, though. So, I do not understand why that question mark ('?') does not appear in the generated module file.
