I am trying to get into development and I am learning how to engineer a release so I came up with a point to start with - rebuild slack 10 for P4 and
roll the isos.I have downloaded slackware_source dir and I was looking around for a sript that builds the entire distribution if such thing exists.

I already have information on how to create isos and experimented with that using the binary distribution. So my search is pretty much for the main script that builds the entire distribution. Once I get to that point I will be able to specify the right gcc flags and etc.

Any pointers or information is appreciated.

Slack is a great distro, but as far as I know, there isn't a script like you are looking for.

It sounds like you might be more interested in looking at linuxfromscratch.org. There you will learn a lot and can 'roll your own' distro.

Good luck!
