unify these scripts: build, modify and update

unify them, by turning them into symlinks pointing
to a generic script named lbmk

the script named lbmk is a fork of the script
named "build", which just checks argument 0 and adapts
accordingly

all of these core scripts had the exact same overall
logic, and they are thus compatible
