mx32 is in the patch more or less just to have it. I also do not need
it for the VirtualBox stuff. It was more an exercise when doing
multilib as the configure options and CFLAGS are different to m32 as
well as to m64.
Alain was interested in mx32 to limit memory usage of tasks to 4GB on
a large system with 32 or 64 GB memory.
