I stumbled on another option today.  Take a look at target_is_uclinux
in m68klinux-tdep.c.

This is a property of the target, not reflected in the gdbarch,
unfortunately.  So we don't know it when we're initializing a
gdbarch and we can't record the result with the gdbarch.  We
might have to put a function pointer in the tdep structure
which returns the right register to use.
