 833    GDB targets (*-tdep.c) can register an interest in a specific
 834    architecture.  Other GDB components can register a need to maintain
 835    per-architecture data.
 836
 837    The mechanisms below ensures that there is only a loose connection
 838    between the set-architecture command and the various GDB
 839    components.  Each component can independantly register their need
 840    to maintain architecture specific data with gdbarch.
 841
 842    Pragmatics:
 843
 844    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
 845    didn't scale.
 846
 847    The more traditional mega-struct containing architecture specific
 848    data for all the various GDB components was also considered.  Since
 849    GDB is built from a variable number of (fairly independant)
 850    components it was determined that the global aproach was not
