Problem: Alpha miscompile when figuring out if alloca.h is present.
This shows up on Alpha32 (Interix).

Fix: Test for whether alloca.h is used should take results of configure
(in auto-host.h).  The prior code was getting it wrong in my case.

	* xm-alpha.h(alloca.h): Add Interix to list of special machines 
	that don't like alloca.h, pending using autoconf results.
