Currently the `mvm` scripts within Linux build directories are failing to properly invoke `checkSCCSversion` because their those directories are nested three levels deep rather than two (as in other platforms).

To fix, update all `mvm` scripts within three-level nested linux build directories to invoke `../../../scripts/checkSCCSversion`

rather than `../../scripts/checkSCCSversion`

I believe this can be accomplished by executing the following one-liner from the repo root: ``` for f in $(find . -name mvm -exec grep -q checkSCCS {} ; -print | awk -F/ 'NF == 5 { print $0 }') ; do printf "g/checkSCCSversion/s/..//&..//\nw\nq" | ed ${f} ; done ```
