[Wien] wien2k.v09.2 on a single node shared memory machine

[Peter Blaha]

You are "right", the latest siteconfig_lapw has a bug and does not honor 
the shared memory settings during installation.

Nothing else was changed in the code and you can fix this by adding a 
line to $WIENROOT/parallel_options:
setenv USE_REMOTE 0

PS: Aparently hardly anybody uses the shared memory option, because this 
restricts the use of WIEN2k on more than one PC.

PPS: There is a new setting  MPI_REMOTE, which directs/avoids calling 
the mpirun command via ssh.
