[OMPI users] Adding libraries to wrapper compiler at run-time

[Jeremiah Willcock]

The Open MPI FAQ shows how to add libraries to the Open MPI wrapper 
compilers when building them (using configure flags), but I would like to 
add flags for a specific run of the wrapper compiler.  Setting OMPI_LIBS 
overrides the necessary MPI libraries, and it does not appear that there 
is an easy way to get just the flags that OMPI_LIBS contains by default 
(either using -showme:link or ompi_info).  Is there a way to add to the 
default set of OMPI_LIBS rather than overriding it entirely?  Thank you 
for your help.
