fix LD_LIBRARY_PATH for "make check"

[ompiteam]

In the file lib/MTT/MPI/Install/OMPI.pm MTT before running the check deletes the LD_BIRARY_PATH to avoid any problems with other librarires. I run into the problem that is mentioned in the comment with the compiler that needs libs of the LD_LIBRARY_PATH.

I think it should be possible to avoid the deletion of the LD_LIBRARY_PATH and and the problems with other libraries. If we simple prepend the MTT paths to the LD_LIBRARY_PATH then it is supposed to work, because in this case the MTT libs are always infront of all the others libs in the LD_LIBRARY_PATH.

(In [230]) Fixes #22. Instead of deleting LD_LIBRARY_PATH, just prepend our
$libdir. Also, when looking for the bindings, ensure to ''prepend''
the libdir to LD_LIBRARY_PATH, not ''append'' it.
