RFA: emit extern declaration for @arch@_cgen_hw_table


This is the second part of the possible kludge.  With these two
changes, I can traverse the hardware table and find the register sets
available to me.

	* desc-cpu.scm (gen-hw-table-decls): Emit an 'extern' declaration
	for @arch@_cgen_hw_table.  GDB needs to be able to find this.
