minimal build fixes for uml (fallout from x86 merge)
a) include/asm-um/arch can't just point to include/asm-$(SUBARCH) now
b) arch/{i386,x86_64}/crypto are merged now
c) subarch-obj needed changes
d) cpufeature_64.h should pull "cpufeature_32.h", not <asm/cpufeature_32.h>
since it can be included from asm-um/cpufeature.h
e) in case of uml-i386 we need CONFIG_X86_32 for make and gcc, but not
for Kconfig
f) sysctl.c shouldn't do vdso_enabled for uml-i386 (actually, that one
should be registered from corresponding arch/*/kernel/*, with ifdef
going away; that's a separate patch, though).
With that and with Stephen's patch ("[PATCH net-2.6] uml: hard_header fix")
we have uml allmodconfig building both on i386 and amd64.
