Hmm.  I suppose we could introduce an ia64-linux-tdep.c (with the
appropriate osabi machinery) to set this for linux.  If it was ever
made to work with hpux, there'd be an ia64-hpux-tdep.c file which
would set it to IEEE quad format.

If you feel up to this, go ahead.  Otherwise, just add a comment
to ia64-tdep.c which indicates that the setting is Linux specific
and that other OSes may use other types.  The comment should also
indicate the correct way that it should be handled (via an OS-specific
tdep.c file.)
