Currently sudo only sets PAM_RHOST on Solaris, which had a bug that
triggered when PAM_RUSER was set but PAM_RHOST was not.

I used to set PAM_RHOST on all PAM systems but on Linux it resulted
in a DNS lookup via libaudit.  I don't know if that is still the
case.  I suppose it could be changed to a sudoers setting.
