[ewg] MVAPICH2 SRPM update

[Shaun Rowland]

I've updated the MVAPICH2 SRPM to mvapich2-0.9.8-12.src.rpm in response
to the following bug entry:

https://bugs.openfabrics.org/show_bug.cgi?id=657

This is an extremely minor fix for C based shell users only. The SRPM
only contains two files: the source tar.gz file and the mvapich2.spec
file. This updated SRPM is identical to the -11 version, except that the
mpivars.csh file generated by the mvapich2.spec file now checks for the
existence of $path and $MANPATH and sets them properly in each case, and
there's also a fix for setting $MANPATH (I was doing it incorrectly).
This is the same sort of check that's in the ofed.csh file.

When I tested this initially, I had $MANPATH set and it worked -
however, the problem only manifests itself if these variables are not
previously defined when the settings are sourced. I was also setting
$MANPATH incorrectly in the mpivars.csh file. This seems to cause tcsh
to stop processing the rest of the user login files if either of the
variables are not defined, so it's a problem for tcsh users. This could
affect MVAPICH too, but only $path is set there, and I doubt it'd ever
be undefined at that point.

Except for this change, everything else: the source code and the
majority of the SPEC file concerning the build, etc. are identical. I've
tested a full install myself. If we could get this included in the final
release, that'd be a good thing for any tcsh users.
