Default HELP !!! Build Android without SElinux support

Please Please help been smashing brains out on google trying to find this

Am trying to build various ROMs without selinux support, i noticed a while back in 4.1 there was a selinux build flag in one of the thousands .mk files in the android source tree, which seemed to be a global switch to enable selinux (modules i assume ).
With 4.3 and 4.4 selinux seems more integrated, is the SElinux env var still there ?,if not can i just build a NO SElinux kernel and remove the selinux components from the manifests ?
SElinux has considerable userland components, do i need to clean up the init to remove refs as well as remove the binaries ?

Any info and help would be greatly appreciated thanks
