Description of problem:
Product info report show wrong "host-cpu-arch" on amd64 architecture with 32-bit version of java (example: "Linux 32-bit x86" version of IBM JDK 8). Host-cpu-arch is probably generated by JDK version.

Steps to Reproduce:

1. use 32bit java on 64bit architecture of CPU
2. get fresh EAP from zip
3. ./standalone.sh
4. ./jboss-cli.sh -c
5. :product-info

Actual results:

        ...
        "host-cpu" => {
            "host-cpu-arch" => "x86",
            "host-core-count" => 8
        },
        ...

Expected results:
Correct value for "host-cpu-arch":

        ...
        "host-cpu" => {
            "host-cpu-arch" => "amd64",
            "host-core-count" => 8
        },
        ...

Additional info:
Architecture from product report is architecture of java (not architecture of CPU). There should be at least something like "host-cpu-arch (generated by JVM)" in product report.
