1058    GDB targets (*-tdep.c) can register an interest in a specific

1060    per-architecture data.

1063    between the set-architecture command and the various GDB

1068
1069    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1070    didn't scale.
1071
1072    The more traditional mega-struct containing architecture specific
1073    data for all the various GDB components was also considered.  Since
1074    GDB is built from a variable number of (fairly independant)
