64-bit requirement

[Weijun Wang]

Thanks for the answer. I build again and finally get a runnable JRE, but there are still some problems:

1. No matter what ARCH is, the target is always universal.

make/hotspot-rules.gmk:

 68 ifeq ($(PLATFORM), macosx)
 69   HOTSPOT_TARGET = universal_product
 70 endif

jdk/make/common/shared/Platform.gmk:

280   # Darwin x86 builds are i386/amd64 universal.
281   ifeq ($(PLATFORM), macosx)
282       ifneq ($(ARCH), ppc)
283           ARCH=universal
284       endif
285   endif

I have to remove some lines on 64 bit to let hotspot and jdk builds go on.

2. Different path names for 32 bit x86 are used, x86, i386, i586. I have to create some symlinks.
