Why would you want to do that, if it even were possible (which I'm pretty sure
it isn't)?
Like I said earlier, you don't need sysinfo to run an MPI job. So if it isn't
being built, you can ignore it.
If you are having problems building for some reason, then just add this to your
configure:
--enable-mca-no-build=sysinfo
and we won't even try to build it.
