Quite frankly, every time I see something like this, I shudder.

Why?

The bugs in the toolchains tend to be infinite and _really_ annoying.
We'll end up with everything from "gcc-xyz cannot handle it" to
"binutils-abc which was pre-released by RH/Ubuntu/SUSE will SIGSEGV".

And those are the _good_ cases. The bad cases are just silently
miscompiled/linked stuff under certain circumstances.

In other words, I'm not going to merge it without a _lot_ of people
pushing me on it with nice numbers etc. Because I absolutely hate the
tools issues that I'm convinced will happen the moment I merge it.
