	The following fixes a FAIL caused by the fact that the alpha stabs
	configuration didn't use the ".if alpha" code in weird.def.
	* gdb.stabs/weird.def (v_comb): Use type attribute to specify 32
	bit pointer, so the 32 bit version works even on the alpha.
	* gdb.stabs/{alpha.mt,ecoff.mt,aout.sed,hppa.sed,xcoff.sed,weird.def}:
	Remove the stuff which allowed us to have separate versions for
	alpha and everything else.
