How can I enable or disable a maven profile based on whether the VM that is executing maven is a 32 bit or a 64 bit JVM? I tried this:

<activation>
   <os>
       <arch>x86</arch>
   </os>
 </activation>

or amd64 respectively to detect a 32/64 bit VM, but this fails on a 32 bit VM running on a 64 bit Windows as it activates the 64 bit profile.
