It really depends on the type of use - i.e. you may check Fedora
packaging configure options construction in its rpm.spec.

Though some of them are now either defaults or not really usable.

I think the key ones are:  --enable-applib --enable-cmdlib
--enable-dmeventd -enable-udev_sync
and some cluster ones if you need them
--with-clvmd=cman,openais,corosync --enable-cmirrord
