Um, I've picked up the tinycc baton (in my copious free time) and am slowly
trying to get it to build a bootable linux kernel. There's a ways to go, and
I really have no idea what I'm doing, but I have help and even made a release
recently (which is already significantly out of date, largely thanks to David
Wheeler):

Admittedly, a lot of this involves implementing gcc extensions, but gratuitous
use of them when there's a perfectly good c99 way of doing it isn't
necessarily a plus. Fabrice got it as far as tccboot before QEMU ate his
life, we've improved a bit since then, and there's presumably a finite amount
of work left to be done...
