if you look into autotools bbclass then you will see that do_configure
does much more it regenerates the configure scripts before it runs
sometimes thats not a viable option we just want to use whatever
configure is provided in tar and that is what this does.

this if used in a recipe which inherits autotools could be for getting
parallelism out of context during install but not during compile.
again this kind of stuff should be avoided.
