OSX 32/64 bits support for JDK7 patch for review

[Henri Gomez]

Hi to all,

I worked on bringing back universal (32/64 bits) JVM support for JDK7
under OSX, feature who disappears when we switch from macosx-port to
jdk7u.

Please find attached a patch against jdk7/jdk7u4.

Could someone review it ?

OSX need an universal VM, there is so many case where a 32bits VM is
enough and even on 64bits, CompressedPointers are not available with
current base code.

Cheers
