It's a lot of engineering to roll out one's own compilers, especially if one wants to do it correctly.

They are relying on specific hacks in the GCC compilers' backends in order for their rpmbuild back-end tools not to bust. That's lack of insight and lack of architecture: what if I were using Sun Studio compilers for Linux, or intel compilers, or PGI compilers? rpmbuild will bust. They didn't think it through, and they never do. It's so stereotypical of them: for the past 20 years they've been haphazardly hacking, and never learned from their mistakes on how to actually engineer systems and how to architect solutions. Just take a look at the hacks they perform in their .src.rpm's, and it's crystal clear.

And "-Wl,--build-id" work-around I had to pull was just one example. I have many.
