Another handy thing about merge_tasks is that it mostly prevents 
interleaving of configure/compile for builds for different 
architectures. i.e. it stops this from silently producing broken 
executables:

MACHINE=mach1 bitbake pkg -c configure
MACHINE=mach2 bitbake pkg
MACHINE=mach1 bitbake pkg


... but you'd almost have to be trying to shoot yourself in the foot to 
do that by accident.
