Hexagon: updated software/libraries

Hexagon has updated software/libraries. Log out and in again for refreshing modules.

Note that several modules are in the process of changing names. The xt-XXXX modules are being renamed to cray-XXXX (i.e. xt-mpich2 == cray-mpich2).
For a time both names will work.

Full releasenotes are in: http://docs.cray.com/books/S-9401-1209//S-9401-1209.pdf
