Quick answer: not easily.
Long answer: There's not an easy way, but there are some facilities to
help. I believe Oracle uses them when building binaries for Solaris.
There is some documentation available on our Trac wiki:
https://svn.open-mpi.org/trac/ompi/wiki/MultiLib
https://svn.open-mpi.org/trac/ompi/wiki/compilerwrapper3264
The difficulty is that it's up to the user/admin to make sure the correct
arguments are provided, as well as writing the wrapper script files to do
the sharing.
