Client VM for 64 bit linux

[Aekold Helbrass]

Hi All,

So, last time when I asked about 64 bit ClientVM someone explained me that
it's fully compatible, just not build.

I've made 2 patches to build system to build 64 bit client VM for linux.
Unfortunately I do not have windows installation to check if it works
there, but on linux it works fine, runs NetBeans without problems, and for
NetBeans difference between 32 and 64 is huge: 4 seconds cold start against
13 seconds cold start.

Please see 2 files in attachment, they should be applied to hotspot and jdk
repositories.

Regards!
